Abstract
OBJECTIVE To compare different tonsillectomy techniques in terms of postoperative bleeding incidence and postoperative pain. METHODS An arm-based network analysis was conducted using a Bayesian hierarchical model. The primary and secondary outcomes were postoperative bleeding incidence and mean postoperative pain score. RESULTS A total of 6464 patients were included for five different interventions (cold dissection tonsillectomy; extracapsular coblation tonsillectomy; intracapsular coblation tonsillectomy [ICT]; bipolar diathermy tonsillectomy [BDT]; monopolar diathermy tonsillectomy). ICT showed the lowest absolute risk (4.44%) of postoperative bleeding incidence (73.31% chance of ranking first) and the lowest mean postoperative pain score (1.74 ± 0.68) with a 94.0% chance of ranking first, whereas BDT showed both the highest absolute risk of bleeding incidence (10.75%) and the highest mean postoperative pain score (5.67 ± 1.43). CONCLUSIONS ICT seems to offer better postoperative outcomes, in terms of reduced risk of bleeding and reduced pain. Further prospective studies are advised to confirm these findings. LEVEL OF EVIDENCE NA Laryngoscope, 134:1696-1704, 2024.

Abstract
Problem-based learning (PBL) is increasingly being used in medical education globally, but its effectiveness in teaching remains controversial. A randomized controlled trial (RCT) is the method of choice for evaluating its effectiveness. The quality of an RCT has a significant effect on this evaluation, but to date we have not seen an assessment of the quality of RCTs for PBL. Two researchers searched MEDLINE and EMBASE for RCTs addressing PBL in medical education. The overall quality of each report was measured on a 28-point overall quality score (OQS) based on the 2010 revised Comprehensive Standards for Reporting and Testing (CONSORT) Statement. Furthermore, to study the key factors affecting OQS more effectively, a linear regression model of those factors was established using SPSS. After literature screening, 30 RCTs were eventually included and analyzed. The median OQS was 15 (range, 7-20), which meant that half of the items in the revised 2010 CONSORT statement were poorly reported in at least 40% of the RCTs analyzed. The regression model showed that the year of publication of RCTs and the impact factors of the journals in which they were published were the main factors affecting OQS. The overall quality of reporting of RCTs on PBL teaching in medical education was not satisfactory. Some RCTs were subjectively selective in reporting certain items, leading to heterogeneity in quality. It is expected that statisticians will develop new standards more suitable for evaluating RCTs related to teaching research and that editors and peer reviewers will be required to review the relevant RCTs more strictly.

Abstract
The aim of this study was to assess the prognostic value of tumor volume in oropharyngeal squamous cell carcinoma (OPSCC). The study was performed according to the PRISMA guidelines. A total of 1417 patients with a median age of 59.3 years (IQR 57.5−60) were included. The combined Hazard Ratios (HRs) for overall survival (OS) were 1.02 (95% CI, 0.99−1.05; p = 0.21) for primary tumor volume (pTV) and 1.01 (95% CI, 1.00−1.02; p = 0.15) for nodal tumor volume (nTV). Regarding locoregional control (LRC), the pooled HRs were 1.07 (95% CI, 0.99−1.17; p = 0.10) for pTV and 1.02 (95% CI, 1.01−1.03; p < 0.05) for nTV. Finally, the pooled HRs for disease-free survival (DFS) were 1.01 (95% CI, 1.00−1.03; p < 0.05) for pTV and 1.02 (95% CI, 1.01−1.03; p < 0.05) for nTV. In conclusion, pTV and nTV seem not to behave as reliable prognostic factors in OPSCC.

Abstract
Background Randomized controlled trials (RCTs) represent the best evidence in oncology research. Glioblastoma is the most frequent and deadly primary brain tumor, affecting health-related quality of life. An important end point is patient-reported outcomes (PROs). There are no data regarding how well publications of glioblastoma RCTs report PROs. A specific PRO extension of the Consolidated Standards of Reporting Trials (CONSORT) statement was created to improve the quality of reporting. The aim of this study was to evaluate adherence to the CONSORT-PRO statement in reporting RCTs addressing the treatment of patients with glioblastoma. PRO analysis methodology was explored and criteria associated with higher quality of reporting were investigated. Methods From PubMed/MEDLINE and the Cochrane Library databases, all phase 2 and 3 RCTs related to glioblastoma published between 1995 and 2018 were reviewed according to the CONSORT-PRO statements. An overall quality score on a 0 to 100 scale was defined based on these criteria and factors associated with this score were identified. Results Forty-four RCTs were identified as relevant according to predefined criteria. The median overall quality score was 26. No difference was observed regarding reporting quality over the years. CONSORT-PRO items concerning data collection and analysis were poorly reported. Thirty-four trials (77%) used longitudinal data. The most frequent statistical method for PROs analysis was the mean change from baseline (63%). Factors associated with improved overall quality score were the presence of a secondary publication dedicated to PROs results, the statement of any targeted dimensions, and when trials reported results using multiple methods. Conclusion Despite the importance of measuring PROs in patients with glioblastoma, employment of the CONSORT-PRO statement is poor in RCTs.

Analysis of the quality of reporting of randomized controlled trials in anticoagulant versus antiplatelet medication for venous thromboembolism prophylaxis as governed by the CONSORT statement. J Thromb Thrombolysis 2020; 52:138-147.

Abstract
Randomized controlled trials (RCTs) are the gold standard research in evaluating healthcare interventions. The CONSORT (Consolidated Standards of Reporting Trials) statement improves the quality of RCTs in an evidence-based approach. To evaluate the reporting quality of published RCTs concerning the use of anticoagulants versus antiplatelet agents for venous thromboembolism prophylaxis according to the CONSORT statement. Electronic databases were searched for English-language RCTs involving patients who received either anticoagulant or antiplatelet medication for prophylaxis of deep vein thrombosis and pulmonary embolism published from 2000 to 2019. Trials were considered eligible when the included patients received either anticoagulant or antiplatelet medication for primary and secondary prevention of deep vein thrombosis or pulmonary embolism and were randomly assigned to at least two treatment arms. Quality of reporting was assessed using a 37-item questionnaire based on the CONSORT 2010 checklist. Reporting was assessed in 2 publication periods (2000-2009) and (2010-2019). The effect of CONSORT statement in high- and low-ranked medical journals, according to their impact factor, has also been evaluated. The search identified 13 eligible articles for analysis. Only 12 of the 37 items of the checklist were addressed in 75% or more of the studies. Most items concerning the methodological issues were reported by fewer than 50% of the studies. Improvements over time were seen for items that assessed the methodological quality with no statistically significant difference. RCTs published in high-ranked journals showed better quality of reporting. Quality of reporting in RCTs focusing on the use of anticoagulants versus antiplatelet agents for venous thromboembolism prophylaxis remains unsatisfactory. Further improvement of reporting is necessary to assess the validity of clinical research.

Abstract
Background Randomized controlled trials (RCTs) are the cornerstone of modern medical research, and their reporting may not always be optimal. The Consolidated Standards of Reporting Trials (CONSORT) statement is an evidence-based means to improve the quality of RCTs’ reporting by providing a checklist of recommended items. The aim of this study was to assess the reporting quality of published RCTs on the restless legs syndrome (RLS), based on a checklist arising from the CONSORT statement. Methods Medical electronic databases were searched for RCTs involving patients with RLS. Inclusion criteria were follows: articles must have been published in English and RLS patients must have been randomized into a minimum of two treatment cohorts of different medicinal orientations. CONSORT-recommended items were marked as “reported” or “not reported,” and an overall CONSORT compliance metric was calculated. Comparisons among different time periods, CONSORT-endorsing and non-endorsing, and different levels of impact factor journals were made. Results Fifty-four eligible trials, published in 21 different scientific journals, were found. The average CONSORT compliance score was 56.6% (23.68–84.21%). CONSORT-endorsing journals had a mean CONSORT compliance of 58.47%, whereas non-endorsing journals had a mean CONSORT compliance of 50.4%. The median CONSORT compliance for articles published in low- (IF<2), medium- (IF 2-7), and high-ranked (IF>7) journals was 52.63, 56.57, and 59.21%, respectively. Only 14 of the 38 CONSORT items (36.8%) were reported in >75% of the articles. Discussion This study shows that the reporting of RLS-related RCTs is suboptimal, regardless of the time period, the quality of the publishing journal, and the endorsing or non-endorsing of the CONSORT statement.

Abstract
OBJECTIVES The goal of this study is to identify, analyse and classify interventions to improve adherence to reporting guidelines in order to obtain a wide picture of how the problem of enhancing the completeness of reporting of biomedical literature has been tackled so far. DESIGN Scoping review. SEARCH STRATEGY We searched the MEDLINE, EMBASE and Cochrane Library databases and conducted a grey literature search for (1) studies evaluating interventions to improve adherence to reporting guidelines in health research and (2) other types of references describing interventions that have been performed or suggested but never evaluated. The characteristics and effect of the evaluated interventions were analysed. Moreover, we explored the rationale of the interventions identified and determined the existing gaps in research on the evaluation of interventions to improve adherence to reporting guidelines. RESULTS 109 references containing 31 interventions (11 evaluated) were included. These were grouped into five categories: (1) training on the use of reporting guidelines, (2) improving understanding, (3) encouraging adherence, (4) checking adherence and providing feedback, and (5) involvement of experts. Additionally, we identified lack of evaluated interventions (1) on training on the use of reporting guidelines and improving their understanding, (2) at early stages of research and (3) after the final acceptance of the manuscript. CONCLUSIONS This scoping review identified a wide range of strategies to improve adherence to reporting guidelines that can be taken by different stakeholders. Additional research is needed to assess the effectiveness of many of these interventions.

Abstract
PURPOSE Reporting guidelines (eg, Consolidated Standards of Reporting Trials [CONSORT] statement) are intended to improve reporting standards and enhance the transparency and reproducibility of research findings. Despite accessibility of such guidelines, researchers are not required to adhere to them. Our goal was to determine the current status of reporting quality in the medical literature and examine whether adherence of reporting guidelines has improved since the inception of reporting guidelines. MATERIALS AND METHODS Eight reporting guidelines, such as CONSORT, Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), STrengthening the Reporting of OBservational studies in Epidemiology (STROBE), Quality of Reporting of Meta-analysis (QUOROM), STAndards for Reporting of Diagnostic accuracy (STARD), Animal Research: Reporting In Vivo Experiments (ARRIVE), Consolidated Health Economic Evaluation Reporting Standards (CHEERS), and Meta-analysis of Observational Studies in Epidemiology (MOOSE) were examined. Our inclusion criteria included reviews published between January 1996 to September 2016 which investigated the adherence to reporting guidelines in the literature that addressed clinical trials, systematic reviews, observational studies, meta-analysis, diagnostic accuracy, economic evaluations, and preclinical animal studies that were in English. All reviews were found on Web of Science, Excerpta Medical Database (EMBASE), MEDLINE, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). RESULTS Among the general searching of 26,819 studies by using the designed searching method, 124 studies were included post screening. We found that 87.9% of the included studies reported suboptimal adherence to reporting guidelines. Factors associated with poor adherence included non-pharmacological interventions, year of publication, and trials concluding with significant results. Improved adherence was associated with better study designs such as allocation concealment, random sequence, large sample sizes, adequately powered studies, multiple authorships, and being published in journals endorsing guidelines. CONCLUSION We conclude that the level of adherence to reporting guidelines remains suboptimal. Endorsement of reporting guidelines by journals is important and recommended.

Enhancing primary reports of randomized controlled trials: Three most common challenges and suggested solutions. Proc Natl Acad Sci U S A 2018. [PMID: 29531032 DOI: 10.1073/pnas.1708286114] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/18/2022] Open
Abstract
Evidence from a well-designed randomized controlled trial (RCT) is generally considered to be the gold standard that can inform clinical practice and guide decision-making. However, several deficiencies in the reporting of RCTs have frequently been identified, including incomplete, selective, and biased or inconsistent reporting. Such suboptimal reporting may lead to irreproducible results, substantial waste of resources, impaired study validity, erosion of public trust in science, and a high risk of research misconduct. In this article, we present an overview of the reporting of RCTs in the biomedical literature with a focus on the three most common reporting problems: (i) lack of adherence to reporting guidelines, (ii) inconsistencies between trial protocols or registrations and full reports, and (iii) inconsistencies between abstracts and their corresponding full reports. Unsatisfactory levels of adherence to guidelines and frequent inconsistencies between protocols or registrations and full reports, and between abstracts and full reports, were consistently found in various biomedical research fields. A variety of factors were found to be associated with these reporting challenges. Improved reporting can build public trust and credibility of science, save resources, and enhance the ethical integrity of research. Therefore, joint efforts from the various sectors of the biomedical community (researchers, journal editors and reviewers, educators, healthcare providers, and other research consumers) are needed to reduce and reverse the current suboptimal state of RCT reporting in the literature.

Oncologist 2017; 23:337-345. [PMID: 29133516 DOI: 10.1634/theoncologist.2017-0196] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 09/26/2017] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND The randomized controlled trial (RCT) is the gold standard to objectively assess the effect of treatments. To help improve the quality of RCTs, experts established a list of recommendations, the CONsolidated Standards of Reporting Trials (CONSORT) Statement. In this study, we evaluated the implementation of the CONSORT Statement in the field of high-grade gliomas in adult patients and looked for criteria associated with higher quality of RCTs. MATERIALS AND METHODS We searched all high-grade gliomas RCTs published in PubMed between January 1990 and December 2016. The quality of these RCTs was assessed by completing a modified CONSORT Score (CS). RESULTS Ninety-six published RCTs were identified. The median CS was 19.5 on a scale of 0-33. Items were not equally reported. Items regarding the method of randomization or the blinding were reported in less than 25% of RCTs. However, the CS has constantly improved over the years. Before the implementation of the CONSORT Statement in 1996, the median CS was 13, whereas it was 17 for the period 1996-2004 and 22 after 2005. A higher CS was observed when RCTs were published in a journal with an impact factor above 10 (p < .001) or after 2010 (p = .001), when the primary outcome was clearly defined (p < .001) and for RCTs that enrolled more than 200 patients (p = .004). CONCLUSION Although there has been a steady improvement in the CS over the years in the field of high-grade gliomas, a major effort must be made in the reporting methods for randomization and blinding. IMPLICATIONS FOR PRACTICE This study showed that the quality of reporting of randomized control trials (RCTs) concerning the treatment of high-grade gliomas is poor. Factors associated with a better quality of reports were identified and should be incorporated into the design of future RCTs. When clinicians read the results of RCTs, they should be aware of the possible inadequate reporting from these trials and take it into account for the management of their patients. This study identifies how RCTs can be improved in their reporting but also in their design, in order to advance care for patients with high-grade gliomas in the future.

Abstract
BACKGROUND Reporting quality of randomized controlled trial (RCT) abstracts is important as readers often make their first judgments based on the abstracts. This study aims to assess the reporting quality of psychiatry RCT abstracts published before and after the release of Consolidated Standards of Reporting Trials for Abstracts (CONSORT-A) guidelines. METHODS MEDLINE/PubMed search was conducted to identify psychiatric RCTs published during 2005-2007 (pre-CONSORT) and 2012-2014 (post-CONSORT). Two independent reviewers assessed abstracts using a 18-point overall quality score (OQS) based on the CONSORT-A guidelines. Linear regression analysis was conducted to analyze factors associated with reporting quality. RESULTS Among 1,927 relevant articles, 285 pre-CONSORT and 214 post-CONSORT psychiatric RCT abstracts were included for analysis. The mean OQS improved from 6.9 (range: 3-13; 95% confidence interval (CI): 6.7-7.2) to 8.2 (range: 4-16; 95% CI: 7.8-8.5) after the CONSORT-A guidelines. Despite improvement, methods of randomization, allocation concealment, and funding source remained to be insufficiently reported (<5%) even after the release of CONSORT-A. High-impact general medical journals, multicenter design, positive outcome, and structured abstracts were associated with better reporting quality. CONCLUSIONS The reporting quality in psychiatric RCT abstracts, although improved, remains suboptimal. To improve reporting quality of psychiatry RCT abstracts, greater efforts by both investigators and journal editors are required to enhance better adherence to the CONSORT-A guidelines.

Abstract
BACKGROUND The CONSORT Statement is an evidence-informed guideline for reporting randomised controlled trials. A number of extensions have been developed that specify additional information to report for more complex trials. The aim of this study was to evaluate the impact of using a simple web-based tool (WebCONSORT, which incorporates a number of different CONSORT extensions) on the completeness of reporting of randomised trials published in biomedical publications. METHODS We conducted a parallel group randomised trial. Journals which endorsed the CONSORT Statement (i.e. referred to it in the Instruction to Authors) but do not actively implement it (i.e. require authors to submit a completed CONSORT checklist) were invited to participate. Authors of randomised trials were requested by the editor to use the web-based tool at the manuscript revision stage. Authors registering to use the tool were randomised (centralised computer generated) to WebCONSORT or control. In the WebCONSORT group, they had access to a tool allowing them to combine the different CONSORT extensions relevant to their trial and generate a customised checklist and flow diagram that they must submit to the editor. In the control group, authors had only access to a CONSORT flow diagram generator. Authors, journal editors, and outcome assessors were blinded to the allocation. The primary outcome was the proportion of CONSORT items (main and extensions) reported in each article post revision. RESULTS A total of 46 journals actively recruited authors into the trial (25 March 2013 to 22 September 2015); 324 author manuscripts were randomised (WebCONSORT n = 166; control n = 158), of which 197 were reports of randomised trials (n = 94; n = 103). Over a third (39%; n = 127) of registered manuscripts were excluded from the analysis, mainly because the reported study was not a randomised trial. Of those included in the analysis, the most common CONSORT extensions selected were non-pharmacologic (n = 43; n = 50), pragmatic (n = 20; n = 16) and cluster (n = 10; n = 9). In a quarter of manuscripts, authors either wrongly selected an extension or failed to select the right extension when registering their manuscript on the WebCONSORT study site. Overall, there was no important difference in the overall mean score between WebCONSORT (mean score 0.51) and control (0.47) in the proportion of CONSORT and CONSORT extension items reported pertaining to a given study (mean difference, 0.04; 95% CI -0.02 to 0.10). CONCLUSIONS This study failed to show a beneficial effect of a customised web-based CONSORT checklist to help authors prepare more complete trial reports. However, the exclusion of a large number of inappropriately registered manuscripts meant we had less precision than anticipated to detect a difference. Better education is needed, earlier in the publication process, for both authors and journal editorial staff on when and how to implement CONSORT and, in particular, CONSORT-related extensions.

Abstract
Background Despite increasing numbers of RCTs done in China, detailed information on the quality of Chinese RCTs is still missing. The aim of this study was to assess the reporting quality of RSA RCTs and to identify significant predictors of reporting quality. Methods A literature review was conducted with the aim of identifying published RCTs on RSA conducted in China. In order to rate the report quality, we scored 1 for the item of CONSORT 2010 if it was reported and 0 if it was not stated or unclear. An overall quality score (OQS) with a range of 0–15 and a key methodological index score (MIS) with a range of 0–3 were calculated for each trial. Results A total of 98 relevant RCTs were included in the final analysis. The median OQS was 7, with a minimum of 1 and maximum of 12. The general level of OQS was not high, especially among ‘sample size,’ ‘baseline data,’ ‘outcomes and estimation,’ and ‘ancillary analyses,’ all of which had a positive rate of less than 10%. The median MIS was 1 with a minimum of 0 and maximum of 1. ‘Allocation concealment,’ ‘blinding,’ and ‘intention-to-treat analysis’ were mentioned in 1 (1%), 1 (1%) and 69 (70%) of the studies, respectively. In univariate analysis, funding was the only factor associated with an increased OQS. Specifically, the mean OQS increased by approximately 1.52 for manuscripts supported by funding (95% CI: 0.12 – 2.92; p = 0.03). With regard to the MIS, no association was found for any variable. Conclusion RCTs of RSA conducted in China need improvement in order to meet the level of “reporting quality” required by the CONSORT statement.

Abstract
OBJECTIVES The aims of this study were to evaluate the quality of randomized controlled trial (RCT) abstracts published in the field of oncology and identify characteristics associated with better reporting quality. STUDY DESIGN AND SETTING All phase III trials published during 2005-2007 [before Consolidated Standards of Reporting Trials (CONSORT)] and 2010-2012 (after CONSORT) were searched electronically in MEDLINE/PubMed and retrieved for review using an 18-point overall quality score (OQS) for reporting based on the CONSORT for Abstract guidelines. Descriptive statistics followed by multivariate linear regression were used to identify features associated with improved reporting quality. RESULTS The mean OQS was 8.2 (range: 5-13; 95% confidence interval (CI): 8.0, 8.3) and 9.9 (range: 5-18; 95% CI: 9.7, 10.2) in the pre- and post-CONSORT periods, respectively. The method for random sequence generation, allocation concealment, blinding details, and funding sources were missing in pre-CONSORT abstracts and insufficiently reported (<20%) in post-CONSORT abstracts. A high impact factor (P < 0.001) and the journal of publication (P < 0.001) were independent factors that were significantly associated with higher reporting quality on multivariate analysis. CONCLUSION The reporting quality of RCT abstracts in oncology showed suboptimal improvement over time. Thus, stricter adherence to the CONSORT for Abstract guidelines is needed to improve the reporting quality of RCT abstracts published in oncology.

Abstract
OBJECTIVES The objective of this study was to assess whether National Institute of Health Research (NIHR) Health Technology Assessment (HTA)-funded randomised controlled trials (RCTs) published in the HTA journal were described in sufficient detail to replicate in practice. SETTING RCTs published in the HTA journal. PARTICIPANTS 98 RCTs published in the HTA journal up to March 2011. Completeness of the intervention description was assessed independently by two researchers using a checklist, which included assessments of participants, intensity, schedule, materials and settings. Disagreements in scoring were discussed in the team; differences were then explored and resolved. PRIMARY AND SECONDARY OUTCOME MEASURES Proportion of trials rated as having a complete description of the intervention (primary outcome measure). The proportion of drug trials versus psychological and non-drug trials rated as having a complete description of the intervention (secondary outcome measures). RESULTS Components of the intervention description were missing in 68/98 (69.4%) reports. Baseline characteristics and descriptions of settings had the highest levels of completeness with over 90% of reports complete. Reports were less complete on patient information with 58.2% of the journals having an adequate description. When looking at individual intervention types, drug intervention descriptions were more complete than non-drug interventions with 33.3% and 30.6% levels of completeness, respectively, although this was not significant statistically. Only 27.3% of RCTs with psychological interventions were deemed to be complete, although again these differences were not significant statistically. CONCLUSIONS Ensuring the replicability of study interventions is an essential part of adding value in research. All those publishing clinical trial data need to ensure transparency and completeness in the reporting of interventions to ensure that study interventions can be replicated.

Abstract
Purpose The Consolidated Standards of Reporting Trials (CONSORT) guidance was extended in 2004 to provide a set of 10 specific and comprehensive guidelines regarding adverse event (AE) reporting in randomized clinical trials (RCTs). Limited data exist regarding adherence to these guidelines in publications of oncology RCTs. Methods All phase III RCTs published between 2007 and 2011 were reviewed using a 16-point AE reporting quality score (AERQS) based on the 2004 CONSORT extension. Multivariable linear regression was used to identify features associated with improved reporting quality. Results A total of 325 RCTs were reviewed. The mean AERQS was 10.1 on a 16-point scale. The most common items that were poorly reported were the methodology of AE collection (adequately reported in only 10% of studies), the description of AE characteristics leading to withdrawals (15%), and whether AEs are attributed to trial interventions (38%). Even when reported, the methods of AE collection and analysis were highly heterogeneous. The multivariable regression model revealed that industry funding, intercontinental trials, and trials in the metastatic setting were predictors of higher AERQS. The quality of AE reporting did not improve significantly over time and was not better among articles published in journals with a high impact factor. Conclusion Our findings show that some methodologic aspects of AE collection and analysis were poorly reported. Given the importance of AEs in evaluating new treatments, authors should be encouraged to adhere to the 2004 CONSORT guidelines regarding AE reporting.

Abstract
Background Quality assessment of pediatric randomized controlled trials (RCTs) in China is limited. The aim of this study was to evaluate the quantitative trends and quality indicators of RCTs published in mainland China over a recent 10-year period. Methods We individually searched all 17 available pediatric journals published in China from January 1, 2002 to December 30, 2011 to identify RCTs of drug treatment in participants under the age of 18 years. The quality was evaluated according to the Cochrane quality assessment protocol. Results Of 1287 journal issues containing 44398 articles, a total of 2.4% (1077/44398) articles were included in the analysis. The proportion of RCTs increased from 0.28% in 2002 to 0.32% in 2011. Individual sample sizes ranged from 10 to 905 participants (median 81 participants); 2.3% of the RCTs were multiple center trials; 63.9% evaluated Western medicine, 32.5% evaluated traditional Chinese medicine; 15% used an adequate method of random sequence generation; and 10.4% used a quasi-random method for randomization. Only 1% of the RCTs reported adequate allocation concealment and 0.6% reported the method of blinding. The follow-up period was from 7 days to 96 months, with a median of 7.5 months. There was incomplete outcome data reported in 8.3%, of which 4.5% (4/89) used intention-to-treat analysis. Only 0.4% of the included trials used adequate random sequence allocation, concealment and blinding. The articles published from 2007 to 2011 revealed an improvement in the randomization method compared with articles published from 2002 to 2006 (from 2.7% to 23.6%, p = 0.000). Conclusions In mainland China, the quantity of RCTs did not increase in the pediatric population, and the general quality was relatively poor. Quality improvements were suboptimal in the later 5 years.

Abstract
Background Reporting guidelines have been available for the past 17 years since the inception of the Consolidated Standards of Reporting Trials statement in 1996. These guidelines were developed to improve the quality of reporting of studies in medical literature. Despite the widespread availability of these guidelines, the quality of reporting of medical literature remained suboptimal. In this study, we assess the current adherence practice to reporting guidelines; determine key factors associated with better adherence to these guidelines; and provide recommendations to enhance adherence to reporting guidelines for future studies. Methods We undertook a systematic scoping review of systematic reviews of adherence to reporting guidelines across different clinical areas and study designs. We searched four electronic databases (Cumulative Index to Nursing and Allied Health Literature, Web of Science, Embase, and Medline) from January 1996 to September 2012. Studies were included if they addressed adherence to one of the following guidelines: Consolidated Standards of Reporting Trials (CONSORT), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), Quality of Reporting of Meta-analysis (QUOROM), Transparent Reporting of Evaluations with Nonrandomized Designs (TREND), Meta-analysis Of Observational Studies in Epidemiology (MOOSE) and Strengthening the Reporting of Observational Studies in Epidemiology (STROBE). A protocol for this study was devised. A literature search, data extraction, and quality assessment were performed independently by two authors in duplicate. This study reporting follows the PRISMA guidelines. Results Our search retrieved 5159 titles, of which 50 were eligible. Overall, 86.0% of studies reported suboptimal levels of adherence to reporting guidelines. Factors associated with better adherence included journal impact factor and endorsement of guidelines, publication date, funding source, multisite studies, pharmacological interventions and larger studies. Conclusion Reporting guidelines in the clinical literature are important to improve the standards of reporting of clinical studies; however, adherence to these guidelines remains suboptimal. Action is therefore needed to enhance the adherence to these standards. Strategies to enhance adherence include journal editorial policies endorsing these guidelines.

Abstract
BACKGROUND An overwhelming body of evidence stating that the completeness of reporting of randomised controlled trials (RCTs) is not optimal has accrued over time. In the mid-1990s, in response to these concerns, an international group of clinical trialists, statisticians, epidemiologists, and biomedical journal editors developed the CONsolidated Standards Of Reporting Trials (CONSORT) Statement. The CONSORT Statement, most recently updated in March 2010, is an evidence-based minimum set of recommendations including a checklist and flow diagram for reporting RCTs and is intended to facilitate the complete and transparent reporting of trials and aid their critical appraisal and interpretation. In 2006, a systematic review of eight studies evaluating the "effectiveness of CONSORT in improving reporting quality in journals" was published. OBJECTIVES To update the earlier systematic review assessing whether journal endorsement of the 1996 and 2001 CONSORT checklists influences the completeness of reporting of RCTs published in medical journals. SEARCH METHODS We conducted electronic searches, known item searching, and reference list scans to identify reports of evaluations assessing the completeness of reporting of RCTs. The electronic search strategy was developed in MEDLINE and tailored to EMBASE. We searched the Cochrane Methodology Register and the Cochrane Database of Systematic Reviews using the Wiley interface. We searched the Science Citation Index, Social Science Citation Index, and Arts and Humanities Citation Index through the ISI Web of Knowledge interface. We conducted all searches to identify reports published between January 2005 and March 2010, inclusive. SELECTION CRITERIA In addition to studies identified in the original systematic review on this topic, comparative studies evaluating the completeness of reporting of RCTs in any of the following comparison groups were eligible for inclusion in this review: 1) Completeness of reporting of RCTs published in journals that have and have not endorsed the CONSORT Statement; 2) Completeness of reporting of RCTs published in CONSORT-endorsing journals before and after endorsement; or 3) Completeness of reporting of RCTs before and after the publication of the CONSORT Statement (1996 or 2001). We used a broad definition of CONSORT endorsement that includes any of the following: (a) requirement or recommendation in journal's 'Instructions to Authors' to follow CONSORT guidelines; (b) journal editorial statement endorsing the CONSORT Statement; or (c) editorial requirement for authors to submit a CONSORT checklist and/or flow diagram with their manuscript. We contacted authors of evaluations reporting data that could be included in any comparison group(s), but not presented as such in the published report and asked them to provide additional data in order to determine eligibility of their evaluation. Evaluations were not excluded due to language of publication or validity assessment. DATA COLLECTION AND ANALYSIS We completed screening and data extraction using standardised electronic forms, where conflicts, reasons for exclusion, and level of agreement were all automatically and centrally managed in web-based management software, DistillerSR(®). One of two authors extracted general characteristics of included evaluations and all data were verified by a second author. Data describing completeness of reporting were extracted by one author using a pre-specified form; a 10% random sample of evaluations was verified by a second author. Any discrepancies were discussed by both authors; we made no modifications to the extracted data. Validity assessments of included evaluations were conducted by one author and independently verified by one of three authors. We resolved all conflicts by consensus.For each comparison we collected data on 27 outcomes: 22 items of the CONSORT 2001 checklist, plus four items relating to the reporting of blinding, and one item of aggregate CONSORT scores. Where reported, we extracted and qualitatively synthesised data on the methodological quality of RCTs, by scale or score. MAIN RESULTS Fifty-three publications reporting 50 evaluations were included. The total number of RCTs assessed within evaluations was 16,604 (median per evaluation 123 (interquartile range (IQR) 77 to 226) published in a median of six (IQR 3 to 26) journals. Characteristics of the included RCT populations were variable, resulting in heterogeneity between included evaluations. Validity assessments of included studies resulted in largely unclear judgements. The included evaluations are not RCTs and less than 8% (4/53) of the evaluations reported adjusting for potential confounding factors. Twenty-five of 27 outcomes assessing completeness of reporting in RCTs appeared to favour CONSORT-endorsing journals over non-endorsers, of which five were statistically significant. 'Allocation concealment' resulted in the largest effect, with risk ratio (RR) 1.81 (99% confidence interval (CI) 1.25 to 2.61), suggesting that 81% more RCTs published in CONSORT-endorsing journals adequately describe allocation concealment compared to those published in non-endorsing journals. Allocation concealment was reported adequately in 45% (393/876) of RCTs in CONSORT-endorsing journals and in 22% (329/1520) of RCTs in non-endorsing journals. Other outcomes with results that were significant include: scientific rationale and background in the 'Introduction' (RR 1.07, 99% CI 1.01 to 1.14); 'sample size' (RR 1.61, 99% CI 1.13 to 2.29); method used for 'sequence generation' (RR 1.59, 99% CI 1.38 to 1.84); and an aggregate score over reported CONSORT items, 'total sum score' (standardised mean difference (SMD) 0.68 (99% CI 0.38 to 0.98)). AUTHORS' CONCLUSIONS Evidence has accumulated to suggest that the reporting of RCTs remains sub-optimal. This review updates a previous systematic review of eight evaluations. The findings of this review are similar to those from the original review and demonstrate that, despite the general inadequacies of reporting of RCTs, journal endorsement of the CONSORT Statement may beneficially influence the completeness of reporting of trials published in medical journals. Future prospective studies are needed to explore the influence of the CONSORT Statement dependent on the extent of editorial policies to ensure adherence to CONSORT guidance.

Abstract
BACKGROUND The Consolidated Standards of Reporting Trials (CONSORT) guidelines were developed in the mid-1990s for the explicit purpose of improving clinical trial reporting. However, there is little information regarding the adherence to CONSORT guidelines of recent publications of randomized controlled trials (RCTs) in oncology. METHODS All phase III RCTs published between 2005 and 2009 were reviewed using an 18-point overall quality score for reporting based on the 2001 CONSORT statement. Multivariable linear regression was used to identify features associated with improved reporting quality. To provide baseline data for future evaluations of reporting quality, RCTs were also assessed according to the 2010 revised CONSORT statement. All statistical tests were two-sided. RESULTS A total of 357 RCTs were reviewed. The mean 2001 overall quality score was 13.4 on a scale of 0-18, whereas the mean 2010 overall quality score was 19.3 on a scale of 0-27. The overall RCT reporting quality score improved by 0.21 points per year from 2005 to 2009. Poorly reported items included method used to generate the random allocation (adequately reported in 29% of trials), whether and how blinding was applied (41%), method of allocation concealment (51%), and participant flow (59%). High impact factor (IF, P = .003), recent publication date (P = .008), and geographic origin of RCTs (P = .003) were independent factors statistically significantly associated with higher reporting quality in a multivariable regression model. Sample size, tumor type, and positivity of trial results were not associated with higher reporting quality, whereas funding source and treatment type had a borderline statistically significant impact. CONCLUSION The results show that numerous items remained unreported for many trials. Thus, given the potential impact of poorly reported trials, oncology journals should require even stricter adherence to the CONSORT guidelines.

Abstract
BACKGROUND The heterogeneity of neuroendocrine tumours (NETs) makes interpretation of clinical trials in this disease challenging. Our aim was to review the quality of treatment trials in NETs in order to inform the design and reporting of future studies. METHODS We identified studies by searching MEDLINE. We considered all phase II and III trials of systemic antineoplastic treatments published between 2000 and 2011. Information on trial design, study population, end points, statistical considerations and results was abstracted from each article using a standardized form. RESULTS Seven phase III and 39 phase II trials were identified. The make-up of the study population was variable: only 24% of trials included patients with one type of tumour (pancreatic NET or carcinoid tumour), 41% included patients with both tumour types, and 35% of trials included other endocrine cancers. Disease progression at baseline was often not reported and was documented for all patients in 22% of the trials. The functional status of the tumour, tumour differentiation, and Ki67 index were reported in 35, 43, and 15% of trials, respectively. The primary end point was clearly defined in 72% of trials. Identifiable statistical design, and predefined sample size were reported in 74 and 61% of trials, respectively. Conflicts of interest and study sponsorship were reported in 46 and 85% of trials. CONCLUSIONS The quality of the design and reporting of phase II/III NET trials, as described in other cancers, is poor. Future trials should include more homogenous patient populations while adhering to rigorous selection, reporting and interpretation of population and trial parameters.

Abstract
OBJECTIVES To be useable in clinical practise, treatments studied in trials must provide sufficient information to enable clinicians and researchers to replicate. We sought to assess the completeness of treatment descriptions in published randomised controlled trials (RCTs) using a checklist and to determine the extent to which peer reviewers and editors comment on the quality of reporting of treatments. DESIGN A cross-sectional study. SETTING Trials published in the BMJ, a general medical journal. PARTICIPANTS Fifty-one trials published in the BMJ were independently evaluated by two raters using a checklist. Reviewers' and editors' comments were also assessed for statements on treatment descriptions. PRIMARY AND SECONDARY OUTCOME MEASURES Proportion of trials rated as replicable (primary outcome). RESULTS For 57% (29/51) of the papers, published treatment descriptions were not considered sufficient to allow replication. Most poorly described aspects were the actual procedures involved including the sequencing of the technique (what happened and when) and the physical or informational materials used (eg, training materials): 53% and 43% not clear, respectively. For a third of treatments, the dose/duration of individual sessions was not clear and for a quarter the schedule (interval, frequency, duration or timing) was not clear. Although the majority of problems were not picked up by reviewers and editors, when they were detected only about two-thirds were fixed before publication. CONCLUSIONS Journals wanting to publish the research of use to practising healthcare professionals need to pay more attention to descriptions of treatments. Our checklist, may be useful for reviewers, and editors and could help ensure that important details of treatments are provided before papers are in the public domain.

Abstract
Objective: A common disorder requiring symptom palliation in palliative and end-of-life care is cancer. Cancer pain is recognized as a global health burden. This paper sought to systematically examine the extent to which there is an adequate scientific research base on cancer pain and its reporting characteristics in the palliative care journal literature. Materials and Methods: Search conducted in MEDLINE and CINAHL sought to locate all studies published in 19 palliative/ hospice/ supportive/ end-of-life care journals from 2009 to 2010. The journals included were: American Journal of Hospice and Palliative Care, BMC Palliative Care, Current Opinion in Supportive and Palliative Care, End of Life Care Journal, European Journal of Palliative Care, Hospice Management Advisor, Indian Journal of Palliative Care, International Journal of Palliative Nursing, Internet Journal of Pain Symptom Control and Palliative Care, Journal of Pain and Palliative Care Pharmacotherapy, Journal of Palliative Care, Journal of Palliative Medicine, Journal of Social Work in End-of-life and Palliative Care, Journal of Supportive Oncology, Palliative Medicine, Palliative and Supportive Care, and Supportive Care in Cancer. Journal contents were searched to identify studies that included cancer pain in abstract. Results: During the years 2009 and 2010, of the selected 1,569 articles published in the journals reviewed, only 5.86% (92 articles) were on cancer pain. Conclusion: While researchers in the field of palliative care have studied cancer pain, the total percentage for studies is still a low 5.86%. To move the field of palliative care forward so that appropriate guidelines for cancer pain management can be developed, it is critical that more research be reported upon which to base cancer pain therapy in an evidence-based palliative care model.

Abstract
PURPOSE Randomized controlled trials (RCTs) represent the best evidence in oncology practice. The aim of this study was to assess the reporting quality of sarcoma RCTs and to identify significant predictors of quality. PATIENTS AND METHODS Two investigators searched MEDLINE for pediatric and adult bone and soft tissue sarcoma RCTs published between January 1988 and December 2008. The quality of each report was assessed by using a 15-point overall reporting quality score based on 15 items from the revised Consolidated Standards of Reporting Trials (CONSORT) statement (overall quality score [OQS] range, 0 to 15 points). Concealment of allocation, appropriate blinding, and analysis according to intention-to-treat principle were assessed separately because of their crucial methodologic importance by using a 3-point key methodologic index score (MIS; range, 0 to 3). RESULTS We retrieved 72 relevant RCTs that included 16,029 patients. The median OQS was 9.5. Allocation concealment, blinding, and analysis by intent to treat were reported only in 21 (29%), nine (12.5%), and 23 (32%) of the 72 RCTs, respectively. The median MIS was 1 with a minimum of 0 and a maximum of 2. On multivariate analysis, publication after 1996 and high impact factor remained independent and significant predictors of improved OQS. The sole variable associated with improved MIS was the publication of chemotherapy-only trials. CONCLUSION Although the overall quality of sarcoma RCTs reporting has improved over time, reporting of key methodologic issues remains poor. This may lead to biased interpretation of sarcoma trial results.

Abstract
PURPOSE Randomized controlled trials (RCTs) are the best tool to evaluate the effectiveness of clinical interventions. The CONSORT (Consolidated Standards of Reporting Trials) statement is an evidence-based approach to improve the quality of RCTs. The aim of this study was to evaluate the reporting quality of published RCTs concerning myeloid hematologic malignancies according to the CONSORT statement. METHODS PubMed was searched for English-language RCTs involving patients with acute myeloid leukemia (AML), chronic myeloid leukemia (CML) and myelodysplastic syndromes (MDS). Trials were considered eligible when participants were randomly assigned to at least two treatment arms and included patients with AML, CML or MDS. Quality of reporting was assessed using a 24-item questionnaire based on the CONSORT checklist. Reporting was assessed in one pre-CONSORT (1988-1995) and one post-CONSORT (1996-2008) period. The effect of CONSORT statement in high- and low-ranked journals, according to their impact factor, has also been evaluated. RESULTS The search identified 261 eligible articles for analysis. Only 13 of the 24 items of CONSORT statement were addressed in 75% or more of the studies. Most items concerning the methodological issues were reported by fewer than 50% of the studies. Significant improvements over time were seen for items that assessed the methodological quality, while RCTs published in high-ranked journals showed better quality of reporting. CONCLUSIONS Quality of reporting in RCTs focusing on myeloid malignancies remains unsatisfactory. Further improvement of reporting is necessary to assess the validity of clinical research.

Abstract
BACKGROUND AND OBJECTIVES Many randomized controlled trials (RCTs) were conducted to evaluate the efficacy of DanShen (Salvia miltiorrhizae, an herbal medicine) on ischemic vascular diseases (IVD). However, there has been no systematic evaluation of the quality of DanShen RCTs so far. The aims of this study were (1) to assess the quality of DanShen RCTs on IVD published in mainland China from 1998 to 2007 and (2) to explore the factors correlating with the quality. DESIGN A number of Chinese databases were searched, and most of DanShen RCTs on IVD were collected. According to CONSORT for TCM (Consolidated Standards for Reporting of Trials for Traditional Chinese Medicine) and the Jadad scale, the quality assessment and data abstraction were performed independently by two reviewers. One-way analysis of variance and Pearson correlation analysis were applied to explore the association between basic characteristic and the quality of the RCTs. RESULTS One hundred and fifty (150) DanShen RCTs were identified finally. The mean (standard deviation) score of 150 DanShen RCTs assessed by CONSORT for TCM was 23.87 (3.68), and 1.94 (0.82) by the Jadad scale, respectively. Only 6.7% (10/150) of RCTs were identified with high quality (Jadad score > or =4). Authors' affiliation, publication journal, sample size, and follow-up time were correlated with the quality of DanShen RCTs. CONCLUSIONS The quality of DanShen RCTs in mainland China has not been improved significantly over recent years, and the overall quality of DanShen RCTs is still poor.

Abstract
BACKGROUND Randomized controlled trials in plastic surgery have not been analyzed comprehensively. We analyzed plastic surgical randomized controlled trials with respect to reporting standards, methodologic quality, and impact on the specialty. METHODS Randomized controlled trials published from 1986 to 2006 in three major plastic surgery journals were scored for quality and impact using the Consolidated Standards of Reporting Trials checklist, the Jadad criteria, citation numbers, and other parameters. The associations between the quality scores and multiple independent parameters, including trial impact, were explored. The relative impact of randomized controlled trials in plastic surgery was compared with that in other specialties. RESULTS A total of 163 randomized controlled trials were evaluated. The average Consolidated Standards of Reporting Trials and Jadad scores were 49 percent and 2.3, respectively. There were deficiencies in the reporting of parameters that influence bias and statistical significance. Randomized controlled trials with high impact or high methodologic quality had higher reporting scores. However, the quality and impact scores did not correlate with the number of participants, subject category, country of origin, or year or journal of publication. Nonsurgical trials had significantly higher quality and impact than surgical trials. Randomized controlled trials in plastic surgery had relatively lower impact as compared with randomized controlled trials in other specialties. CONCLUSIONS The reporting and methodologic standards of randomized controlled trials in plastic surgery need improvement. Standards could be improved if well-accepted reporting and methodologic criteria are considered when designing and evaluating randomized controlled trials. Instituting higher standards may improve the impact of randomized controlled trials and make them more influential in plastic surgery.

Abstract
Purpose Several publications showed that the standards for reporting randomized clinical trials (RCTs) might not be entirely suitable. Our aim was to evaluate the reporting of survival end points in cancer RCTs. Methods A search in MEDLINE databases identified 274 cancer RCTs published in 2004 in four general medical journals and four clinical oncology journals. Eligible articles were those that reported primary analyses of RCT with survival end points. Methodologists reviewed and scored the articles according to seven key points: prevalence of complete definition of survival end points (time of origin, survival events, censoring events) and relevant information about their analyses (estimation or effect size, precision, number of events, patients at risk). Concordance of key points was evaluated from a random subsample. Results After screening, 125 articles were selected; 104 trials were phase III (83%) and 98 publications (78%) were obtained from oncology journals. Among these RCTs, a total of 267 survival end points were recorded, and overall survival (OS) was the most frequent outcome (118 terms, 44%). Survival terms were totally defined for 113 end points (42%) in 65 articles (52%). Accurate information about analysis was retrieved for 73 end points (27%) in 40 articles (32%). The less well-defined information was the number of patients at risk (55%). The reliability was good (κ = 0.72). Finally, according to the key points, optimal reporting was found in 33 end points (12%) or 10 publications. Conclusion A majority of articles failed to provide a complete reporting of survival end points, thus adding another source of uncontrolled variability.

Abstract
PURPOSE To evaluate the reporting quality of key methodological items in randomized controlled trials (RCTs) in four general clinical ophthalmology journals. METHODS The reporting of 11 key methodological items in RCTs published in American Journal of Ophthalmology, Archives of Ophthalmology, British Journal of Ophthalmology and Ophthalmology in the year 2005 was assessed. RESULTS Sixty-seven eligible RCTs were assessed and the mean number of items reported was 6.3 per RCT. No significant difference in the mean number of items reported was found between the four journals (P=0.20). The most frequently reported item was ethics approval and informed consent (97.0%), followed by masking status (85.1%), description of withdrawals (76.1%), adverse events (73.1%), and intention-to-treat analysis (71.6%). Details on sequence generation, randomization restriction, allocation concealment, allocation implementation, patient flow diagrams, and sample size calculation were reported in <50% of the RCTs assessed. Both sample size and page length of the RCTs correlated with the number of methodological items reported (P=0.024 and P=0.008, respectively). CONCLUSIONS Similar to other specialties, rooms for improvement exist in the reporting of key methodological items of RCTs in clinical ophthalmic journals. Stricter adoption of the CONSORT statement might enhance the reporting quality of RCTs in ophthalmic journals.

Abstract
PURPOSE This study was designed to analyze the characteristics and the quality of reporting of randomized, controlled trials published during the last ten years on fecal incontinence. METHODS An electronic search for all randomized, controlled trials on fecal incontinence was undertaken by using the MEDLINE database via PubMed. The data collected were divided into general data, characteristics of reporting, methodology quality assessment using the Jadad scale and a validated methodology quality score (MINCIR score), evaluation of the items published in the CONSORT statement, and the journal impact factor. Reports were divided into two groups: published articles from 1996 to 2000 (Group 1), and from 2001 to 2005 (Group 2). RESULTS Forty-two trials fulfilled the inclusion criteria of the study (Group 1, n = 15; and Group 2, n = 27). There were no significant differences in general characteristics of randomized, controlled trials between the two groups. In Group 2, there were a statistically significant higher number of studies that reported a flow chart (P < 0.001), written informed consent (P = 0.008), sample size calculation (P = 0.023), and withdrawals and dropouts (P < 0.001). We found a statistically significant higher score in Jadad scale (P = 0.046) and MINCIR score (P = 0.016) in the published studies in Group 2. Also we found higher journal impact factor of journals that published these randomized, controlled trials during the most recent years (P = 0.04). CONCLUSIONS There is a lack of high-quality reported randomized, controlled trials on fecal incontinence during the last ten years. Reports of randomized, controlled trials involving patients with fecal incontinence published after 2001 were better reported than in the previous five years.

Abstract
BACKGROUND The number of randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) is increasing. However, there have been few systematic assessments of the quality of reporting of these trials. OBJECTIVE This study was undertaken to evaluate the quality of reporting of RCTs in TCM journals published in mainland China from 1999 to 2004. METHODS Thirteen TCM journals were randomly selected by stratified sampling of the approximately 100 TCM journals published in mainland China. All issues of the selected journals published from 1999 to 2004 were hand-searched according to guidelines from the Cochrane Centre. All reviewers underwent training in the evaluation of RCTs at the Chinese Centre of Evidence-based Medicine. A comprehensive quality assessment of each RCT was completed using a modified version of the Consolidated Standards of Reporting Trials (CONSORT) checklist (total of 30 items) and the Jadad scale. Disagreements were resolved by consensus. RESULTS Seven thousand four hundred twenty-two RCTs were identified. The proportion of published RCTs relative to all types of published clinical trials increased significantly over the period studied, from 18.6% in 1999 to 35.9% in 2004 (P < 0.001). The mean (SD) Jadad score was 1.03 (0.61) overall. One RCT had a Jadad score of 5 points; 14 had a score of 4 points; and 102 had a score of 3 points. The mean (SD) Jadad score was 0.85 (0.53) in 1999 (746 RCTs) and 1.20 (0.62) in 2004 (1634 RCTs). Across all trials, 39.4% of the items on the modified CONSORT checklist were reported, which was equivalent to 11.82 (5.78) of the 30 items. Some important methodologic components of RCTs were incompletely reported, such as sample-size calculation (reported in 1.1% of RCTs), randomization sequence (7.9%), allocation concealment (0.3 %), implementation of the random-allocation sequence (0%), and analysis of intention to treat (0%). CONCLUSION The findings of this study indicate that the quality of reporting of RCTs of TCM has improved, but remains poor.
