[PMID: 39095959 DOI: 10.1111/joor.13824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 07/13/2024] [Accepted: 07/23/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND Poor reporting quality and spin in randomized controlled trial (RCT) abstracts can lead to misinterpretation and distorted interpretation of results. OBJECTIVES This methodological study aimed to assess the reporting quality and spin among RCT abstracts on splint therapy for temporomandibular disorders (TMD) and explore the association between spin and potentially related factors. METHODS The authors searched PubMed for RCTs on splint therapy for TMD. The reporting quality of each abstract was assessed using the original 16-item CONSORT for abstracts checklist. The authors evaluated the presence and characteristics of spin only in abstracts with nonsignificant primary outcomes according to pre-determined spin strategies. Logistic regression analyses were performed to identify factors associated with the presence of spin. RESULTS A total of 148 abstracts were included in the reporting quality evaluation. The mean overall CONSORT score (OCS) was 5.86 (score range: 0-16). Only interventions, objectives and conclusions were adequately reported. Of the 61 RCT abstracts included for spin analysis, spin was identified in 38 abstracts (62.3%), among which 32 abstracts (52.3%) had spin in the Results section and 21 (34.4%) had spin in the Conclusions section. A significantly lower presence of spin was found in studies with exact p-value reporting (OR: 0.170; 95% CI: 0.032-0.887; p = .036) and a two-arm comparison design (OR: 11.777; 95% CI: 2.171-63.877; p = .004). CONCLUSIONS The reporting quality of RCT abstracts on splint therapy for TMD is suboptimal and the prevalence of spin is high. More awareness and joint efforts are needed to improve reporting quality and minimize spin.

Abstract
BACKGROUND Abstracts provide readers a concise and readily accessible information of the trials. However, poor reporting quality and spin (misrepresentation of research findings) can lead to an overestimation in trial validity. This methodological study aimed to assess the reporting quality and spin among randomized controlled trial (RCT) abstracts in pediatric dentistry. METHODS We hand-searched RCTs in five leading pediatric dental journals between 2015 and 2021. Reporting quality in each abstract was assessed using the original 16-item CONSORT for abstracts checklist. Linear regression analyses were performed to identify factors associated with reporting quality. We evaluated the presence and characteristics of spin only in abstracts of parallel-group RCTs with nonsignificant primary outcomes according to pre-determined spin strategies. RESULTS One hundred eighty-two abstracts were included in reporting quality evaluation. The mean overall quality score was 4.57 (SD, 0.103; 95% CI, 4.36-4.77; score range, 1-10). Only interventions, objective, and conclusions were adequately reported. Use of flow diagram (P < 0.001) was the only significant factor of higher reporting quality. Of the 51 RCT abstracts included for spin analysis, spin was identified in 40 abstracts (78.4%), among which 23 abstracts (45.1%) had spin in the Results section and 39 in the Conclusions Sect. (76.5%). CONCLUSIONS The reporting quality of RCT abstracts in pediatric dentistry is suboptimal and the prevalence of spin is high. Joint efforts are needed to improve reporting quality and minimize spin.

Abstract
STUDY OBJECTIVES 'Spin', using reporting strategies to distort study results, can mislead readers of medical research. This study aimed to evaluate the prevalence and characteristics of 'spin' among randomised controlled trial (RCT) abstracts published in sleep medicine journals, and to identify factors associated with its presence and severity. METHODS The search for RCTs published between 2010 and 2020 were conducted in seven reputable journals of sleep medicine. Abstracts of RCTs with statistically nonsignificant primary outcomes were included and analysed for 'spin', according to pre-determined 'spin' strategies. Chi-square tests or logistic regression analyses were performed to detect the association between characteristics of included abstracts and the presence and severity of 'spin'. RESULTS A total of 114 RCT abstracts were included in this study, of which 89 (78.1%) were identified as having at least one type of 'spin' strategy. Sixty-six abstracts (57.9%) had 'spin' in the Results section, 82 (71.9%) abstracts presented with 'spin' in the Conclusions section. The presence of 'spin' varied significantly among RCTs based on the different categories of research area (P=0.047) and the statistician involvement (P=0.045). Furthermore, research area (P=0.019) and funding status (P=0.033) were significant factors associated with the severity of 'spin'. CONCLUSIONS The prevalence of 'spin' is high among RCT abstracts in sleep medicine. This raise the need for researchers, editors and other stakeholders to be aware of the issue of 'spin' and make joint efforts to eliminate it in future publications.

THE REPORTING QUALITY OF SYSTEMATIC REVIEW ABSTRACTS IN LEADING GENERAL DENTAL JOURNALS: A METHODOLOGICAL STUDY. J Evid Based Dent Pract 2023; 23:101831. [PMID: 36914298 DOI: 10.1016/j.jebdp.2022.101831] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Revised: 09/30/2022] [Accepted: 11/22/2022] [Indexed: 12/27/2022]
Abstract
OBJECTIVE To assess the reporting quality of systematic review (SR) abstracts published in leading general dental journals according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Abstracts (PRISMA-A) guidelines, and to identify factors associated with overall reporting quality. METHODS We identified SR abstracts published in 10 leading general dental journals and assessed their reporting quality. For each abstract, an overall reporting score (ORS, range: 0-13) was calculated. Risk ratio (RR) was calculated to compare the reporting quality of abstracts in Pre-PRISMA (2011-2012) and Post-PRISMA (2017-2018) periods. Univariable and multivariable linear regression analyses were performed to identify factors associated with reporting quality. RESULTS A total of 104 eligible abstracts were included. The mean ORS was 5.59 (SD = 1.48) and 6.97 (1.74) respectively in the Pre- and Post-PRISMA abstracts, with statistically significant difference (mean difference = 1.38; 95% CI: 0.70, 2.05). Reporting of the exact P-value (B = 1.22; 95% CI: 0.45, 1.99) was a significant predictor of higher reporting quality. CONCLUSION The reporting quality of SR abstracts published in leading general dental journals improved after the release of PRISMA-A guidelines, but is still suboptimal. Relevant stakeholders need to work together to enhance the reporting quality of SR abstracts in dentistry.

Abstract
BACKGROUND/AIM Abstracts of randomized controlled trials (RCTs) provide a summary of the entire trial report. Their transparent, detailed, and accurate reporting is essential for clinical decision-making and evidence-based dental practice. The aim of this study was to assess the reporting quality and prevalence of spin in abstracts of RCTs in the field of dentofacial trauma. MATERIALS AND METHODS The PubMed database was searched to identify RCT reports published between 2017 and 2021 in the field of dentofacial trauma. The reporting quality of abstracts was assessed according to the 16-item CONSORT for Abstracts checklist and measured with an overall quality score (OQS, range: 0-16). Linear regression analyses were used to identify factors associated with reporting quality. Among the included RCTs, parallel-group RCTs with non-significant primary outcomes were selected for spin assessment using predefined spin strategies. RESULTS One hundred and twelve eligible abstracts were identified and included. The mean OQS was 4.51 (SD, 1.35; 95% CI, 4.26-4.76). Abstracts with more than 250 words (p = .004) and a structured format (p = .032) had significantly better reporting quality. Of the 30 abstracts that were eligible for spin assessment, spin was identified in 23 (76.7%). Among these, spin was observed in the Conclusions sections of 22 abstracts (73.3%) and the Results sections of 9 abstracts (30.0%). CONCLUSIONS Among RCT abstracts in the field of dentofacial trauma, the reporting quality was sub-optimal and the prevalence of spin was relatively high. Strict adherence to the CONSORT for Abstracts guidelines is needed to ensure complete and transparent reporting. Relevant stakeholders need to make concerted efforts to avoid spin.

J Evid Based Dent Pract 2023; 23:101795. [PMID: 36707165 DOI: 10.1016/j.jebdp.2022.101795] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Revised: 09/04/2022] [Accepted: 09/16/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To identify and summarize the use and characteristics of dental patient-reported outcomes (dPROs) and dental patient-reported outcome measures (dPROMs) within randomized controlled trials (RCTs) published in 5 leading orthodontic journals. METHODS A manual search was conducted to identify intervention (therapeutic or preventive) related RCTs published in selected journals between 2015 and 2021. Two authors extracted the characteristics of each included trial, as well as all outcomes and outcome measures used in these trials independently and in duplicate. Thereafter, the use of dPROs and dPROMs was identified and summarized. We classified all dPROs into 2 general types (oral health-related quality of life [OHRQoL] and others) and dPROMs into 3 categories (single-item questionnaires, generic multiple-item questionnaires, and specific multiple-item questionnaires). We also identified whether these dPROMs assessed 4 dimensions of OHRQoL (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact). RESULTS From 4631 examined articles, a total of 315 RCTs were included, of which 76 (24.1%) used dPROs and dPROMs. Eight different dPROs (OHRQoL, patients' satisfaction with treatment, difficulty, compliance, preference, efficacy, duration, and unwanted events) and 34 different dPROMs (including 13 single-item questionnaires, 7 generic multiple-item questionnaires, and 14 specific multiple-item questionnaires) were identified in these trials. OHRQoL was the most commonly used dPRO (n = 71; 93.4%), followed by patients' satisfaction with treatment (n = 10; 13.2%), patient-reported difficulty (n = 5; 6.6%), and patient-reported compliance (n = 4, 5.3%). The 4 most frequently used dPROMs were pain measured with 10 mm Visual Analogue Scale (n = 20; 24.1%), pain measured with Numerical Rating Scale (n = 11; 13.3%), the Feldmann's Questionnaire (2007) (n = 6; 7.2%), and the Oral Health Impact Profile 14 (n = 5; 6.0%). CONCLUSION Only about one-fourth of RCTs published in leading orthodontic journals can reflect patients' perspectives. OHRQoL was the most commonly used dPRO in these trials. Substantial heterogeneity exists among dPROMs used for OHRQoL assessment. Efforts are needed from researchers, reviewers, editors and other stakeholders to promote the wide and standardized use of dPROs in orthodontic research.

[PMID: 36251569 DOI: 10.1111/clr.14011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 07/16/2022] [Accepted: 10/08/2022] [Indexed: 12/13/2022]
Abstract
OBJECTIVES The objective of this study is to assess the reporting and methodological quality of split-mouth trials (SMTs) in oral implantology published during the past 10 years, and to investigate whether there was any improvement over time. MATERIALS AND METHODS We searched PubMed for SMTs in oral implantology published during 2011-20. We used CONSORT 2010, its extension for within-person trial (WPT), and an SMT-specific methodological checklist to assess trial reporting quality (TRQ), WPT-specific reporting quality (WRQ), and SMT-specific methodological quality (SMQ), respectively. Binary scores were given to each item, and total scores of TRQ (range 0-32), WRQ (0-15), and SMQ (0-3) were calculated for each study. Multivariable regression analyses were performed to compare the quality of SMTs published before (2011-17) and after (2018-20) the release of CONSORT for WPT. RESULTS Seventy-nine SMTs were included. The mean TRQ, WRQ, and SMQ were 16.4, 6.7, and 1.3, respectively. Less than one-third (n = 25, 31.6%) reported the rationale for using split-mouth designs. Only 4 (5.1%) trials adequately conducted sample size calculation, and 40 (50.6%) used appropriate statistical methods that considered dependency and clustering of data. In multivariable analyses, compared with 2011-17, studies published in 2018-20 had significantly higher TRQ (p = .044), while WRQ and SMQ did not show improvement. CONCLUSIONS The reporting and methodological quality of SMTs in oral implantology need to be improved. Joint efforts are needed to improve the reporting and methodology of SMTs in this field.

Abstract
OBJECTIVE To assess the presence and characteristics of spin in recently published RCT abstracts in operative dentistry and to investigate potential factors associated with the presence of spin. METHODS AND MATERIALS The PubMed database was searched to identify parallel-group RCTs published between 2015 and 2019 in the field of operative dentistry, which compared two or more groups and had nonsignificant results for the primary outcome. Two authors evaluated independently the presence and characteristics of spin among these abstracts. Multivariable logistic regression analyses were conducted to identify factors associated with the presence of spin in the Results and the Conclusions sections, respectively. RESULTS A total of 77 RCT abstracts were included, among which 58 (75.3%) showed at least one type of spin. Spin was identified in the Results and Conclusions sections of 32 (41.6%) and 45 (58.4%) abstracts, respectively. 19 RCTs (24.7%) presented spin in both the Results and the Conclusions section of abstracts. The presence of spin in the Results section of abstracts was significantly associated with source of funding (OR=8.10; p=0.025) and number of treatment arms was associated with the presence of spin in the Conclusions section of abstracts (OR=5.66; p=0.005). CONCLUSION The occurrence rate of spin in the sample of operative dentistry RCTs abstracts is high.

A Critical Analysis of Reporting in Systematic Reviews and Meta-Analyses in the Peyronie's Disease Literature. J Sex Med 2022; 19:629-640. [PMID: 35177375 PMCID: PMC9575169 DOI: 10.1016/j.jsxm.2022.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 12/17/2021] [Accepted: 01/12/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND Despite an increasing number of publications on Peyronie's disease (PD), evidence-based clinical decision-making remains challenging due to the small number of well-designed clinical trials. AIM To perform a critical analysis of reporting quality in PD systematic reviews (SR) and meta-analyses (MA). METHODS Study protocol registration was performed on the Open Science Framework platform. In January 2021, a systematic electronic search of the Medline/PubMed, Embase, Ovid, Scopus, Joanne Briggs Institute, and Cochrane databases was performed. Search terms included "Peyronie's disease" and "systematic review OR meta-analysis OR meta-analysis." Eligibility criteria were English-language, relevance to PD and specification of "systematic review" or "meta-analysis" in the title or abstract. Oxford Center for Evidence-Based Medicine levels of evidence were used to classify original studies reviewed within each publication. Risk of bias was assessed using the ROBIS tool. Data were tabulated and reported as means with standard deviation, median with interquartile range and t-testing as appropriate. Strength of association between variables was calculated using Pearson correlation coefficient. Statistical analyses were performed on RStudio (version 1.4.1106). OUTCOMES Outcomes included review type, level of evidence, authorship, journal, publication date, "A MeaSurement Tool to Assess systematic Reviews" (AMSTAR-2) score and "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) score. RESULTS From 1974 to 2021, 340 articles were identified. After review, 17 full length articles were included. Thirteen were SR, 2 MA and 2 was combined. Significant heterogeneity was seen in evidence level of included studies. There was median 54% adherence to AMSTAR-2 criteria and 74% adherence to PRISMA criteria. Overall AMSTAR-2 confidence rating was Critically Low in 11 of 17 studies. Correlation analysis revealed very high positive association between AMSTAR 2 and PRISMA adherence (+0.95). ROBIS revealed "High" concern regarding methods used to collect data and appraise 12/17 studies (71%), and "High" concern regarding synthesis and findings in 8 of 17 studies (47%). CLINICAL IMPLICATIONS Many SR include markedly heterogenous levels of evidence and fail to meet accepted methodological criteria for reporting. STRENGTHS AND LIMITATIONS Main strengths include extensive literature review and analysis of standardized study reporting. One limitation is that aggregate scoring of AMSTAR-2 and PRISMA is not intended as primary method of quality assessment; however effect was minimized by reporting critical domains, overall quality assessments and specifics on globally poorly reported domains. CONCLUSION More high quality randomized controlled PD trials are necessary; SR and MA should focus on these studies alone. Bole R, Gottlich HC, Ziegelmann MJ, et al.

Abstract
The extension of the Consolidated Standards of Reporting Trials (CONSORT) statement provides guidelines for abstracts of randomized controlled trials (RCTs). This study was done to assess the reporting quality of abstracts of RCTs, on procedural sedation in children and identify factors associated with better quality. A PubMed search was conducted from inception of database till July 2017 to identify RCTs on procedural sedation in children. Search terms used were (procedural [All Fields] AND sedation [All Fields]) AND ("child" [MeSH Terms] OR "child" [All Fields] OR "children" [All Fields]) were included in the analysis, while primary RCTs, published in the English language unstructured abstracts, secondary analysis of primary RCTs and studies not exclusively on children we excluded. Our search strategy initially yielded 582 abstracts. Out of these, 535 abstracts were excluded. 47 articles were included in the final analysis. We extracted basic information and data on CONSORT items from abstracts. Each abstract was assessed using a 16-item composite abstract score (CAS) based on the CONSORT guidelines. This abstract quality was further explored by Method Score and by Result Score. Regression analysis was conducted to analyze factors associated with reporting quality. In majority of the abstracts, only objectives and conclusion were adequately reported. Inadequately reported items in >90% of abstracts included randomization, trial status, registration & funding. There was no significant difference in the CAS of abstracts (mean ± SD) published in & before 2008 (12.63 ± 4.0), to those published after 2009 (12.48 ± 4.23). Similarly, there was no significant difference in Result Score and Method Score of the abstracts. After the publication of 'CONSORT for abstracts' guideline, the quality of abstracts of RCTs on procedural sedation has shown suboptimal improvement. We suggest stricter adherence to guidelines by editors and reviewers. A checklist for adherence to CONSORT guidelines could be introduced during submission for the same.

Abstract
BACKGROUND Abstracts of scientific articles should be accurate and detailed in summarizing the information in the full-text because they are the first article section the reader examines. This study assessed the reporting quality of randomized controlled trials (RCTs) abstracts related to implant dentistry and examined associations between reporting quality and study characteristics. METHODS On the 17th of January 2021, we searched the PubMed database for abstracts of RCTs published in high-ranked periodontology and implant dentistry journals from 2016 to 2021. For each abstract, we assessed if the Consolidated Standards of Reporting Trials for abstracts (CONSORT-A) checklist items were reported completely, partially, or not reported. An Overall CONSORT Score (OCS) and relative score (OCS%) were calculated as a proxy to checklist adherance. Linear regression models were fitted to analyze associations between trial characteristics and completeness of reporting. RESULTS Four-hundred and thirty four of the 678 retrieved abstracts were eligible for inclusion. The mean OCS and OCS% were 6,23 (standard deviation [SD] = 1.56) or 41.5% (SD = 10.4), respectively. Items most frequently reported included the title (n = 434; 100%), intended intervention (n = 425; 98%) and conclusions (n = 430; 99%). Participant allocation, blinding, and trial registration were rarely completely reported with frequencies of 2%, 3% and 4%, respectively. We found that number of authors, continent, type of RCT, number of centers, report of ethical approval, funding, structure and length of the abstract were associated with better abstract reporting. CONCLUSION The reporting quality of abstracts in RCTs related to implant dentistry is suboptimal. Journals should start to incorporate and endorse the use of the CONSORT-A guidelines in their instructions to authors to enhance reporting quality. This article is protected by copyright.

Abstract
OBJECTIVES To identify the presence and characteristics of spin (using reporting strategies to distort study results and mislead readers) within randomized controlled trial (RCT) abstracts published in orthodontic journals, and to explore the association between spin and potentially related factors. METHODS A manual search was conducted to identify abstracts of RCTs with statistically non-significant primary outcomes published in five leading orthodontic journals between 2015 and 2020. Spin in the Results and Conclusions sections of each included abstract was evaluated and categorized according to pre-determined spin strategies. Logistic regression analyses were employed to explore the association between spin and relevant factors. RESULTS A total of 111 RCT abstracts were included, of which 69 (62.2 per cent) were identified with spin. In the Results section, 47 (42.3 per cent) abstracts had spin, and 'focusing on significant within-group comparison for primary outcomes' was the most frequent spin strategy. In the Conclusions section, 57 (51.4 per cent) abstracts presented spin, with the most common strategy being 'claiming equivalence or non-inferiority for statistically nonsignificant results'. According to multivariable logistic regression analysis, a significantly lower presence of spin was found in studies with international collaboration (odds ratio [OR]: 0.331, 95 per cent confidence interval [CI]: 0.120-0.912, P = 0.033) and trial registration (OR: 0.336, 95 per cent CI: 0.117-0.962, P = 0.042). CONCLUSION The prevalence of spin is high among RCT abstracts in orthodontics. Clinicians need to be aware of the definition and presence of spin. Concerted efforts are needed from researchers and other stakeholders to address this issue.

Abstract
AIMS To assess in each European country the correlation between the number of Network of Erasmus-Based European Orthodontic Postgraduate Programmes (NEBEOP) members and orthodontic research activity. Secondary objectives were to describe and quantify Europe's orthodontic research. MATERIALS AND METHODS Articles published between 2014 and 2018 in 4 major orthodontic journals (American Journal of Orthodontics and Dentofacial Orthopedics, European Journal of Orthodontics, The Angle Orthodontist, Orthodontics and Craniofacial Research) and oral presentation abstracts of five European Orthodontic Society (EOS) congresses were analysed. For each European country, the total number of orthodontic programmes and NEBEOP memberships were collected. Descriptive statistics were performed, and Spearman correlation coefficients and risk ratios were calculated. RESULTS 2039 articles and 261 oral presentation abstracts were included. Correlation coefficients between national number of publications, oral presentations, sum of these, all adjusted for population, and number of NEBEOP members in each country were 0.64, 0.65 and 0.62, respectively. Risk ratios were all above 1 and statistically significant for number of NEBEOP memberships per country, indicating positive associations with national orthodontic research productivity. Europe accounted for 30.5% of publications and 68.6% of oral presentations at EOS congresses during this period. European orthodontic research was not evenly distributed, since 9 countries were responsible for around 80% of the output. CONCLUSIONS A positive association was found between number of NEBEOP programmes and national research activity. These results could be an additional argument to support similar pan-European initiatives and guidelines for postgraduate education, not only in orthodontics but in all other dental specialties.

Abstract
OBJECTIVES To assess the reporting quality of split-mouth trials (SMTs) in orthodontic journals, and to identify factors associated with better reporting. MATERIALS AND METHODS Seven leading orthodontic journals were hand searched for SMTs published during 2015-19. The CONSORT 2010 guideline and CONSORT for within-person trial (WPT) extension were used to assess the trial reporting quality (TRQ) and WPT-specific reporting quality (WRQ) of included SMTs, respectively. A binary score (0 or 1) was given to each item of the guidelines, and total scores were calculated for TRQ (score range, 0-32) and WRQ (score range, 0-15). Univariable and multivariable linear regression analyses were performed to identify factors associated with TRQ and WRQ. RESULTS A total of 42 SMTs were included. The mean overall scores for TRQ and WRQ were 16.8 [standard deviation (SD) 7.1] and 5.6 (SD 2.3), respectively. Only 11 SMTs (26.2%) presented the rationale for using a split-mouth design. Key methodological items including random sequence generation (22/42, 52.4%), allocation concealment (9/42, 21.4%), and blinding (20/42, 47.6%) were poorly reported. Only six SMTs (14.3%) used a paired method for sample size calculation, and half (21/42, 50.0%) considered the dependent nature of data in statistical analysis. In multivariable analyses, higher TRQ and WRQ were both significantly associated with journal, reported use of CONSORT and funding status. CONCLUSIONS The reporting quality of SMTs in orthodontics has much room for improvement. Joint efforts from relevant stakeholders are needed to improve the reporting quality of SMTs and reduce relevant avoidable research waste.

Abstract
OBJECTIVE To evaluate the adherence of veterinary randomized controlled trial (RCT) abstracts to the recommendations on minimum abstract information included in the Consolidated Standards of Reporting Trials (CONSORT) checklist for RCT abstracts and to identify characteristics associated with the number of CONSORT items reported. SAMPLE 212 abstracts representing all RCTs published in 5 general veterinary journals in 2013 and 2018. PROCEDURES 2 investigators independently assessed whether each of the 15 CONSORT checklist items for abstracts applicable to veterinary medicine was reported. Generalized linear mixed models were built to explore associations of selected variables with the total number of checklist items reported. RESULTS Abstracts included a median of 5 checklist items (range, 2 to 10 items). None met the recommendations for reporting participant recruitment and funding source. Less than 25% of abstracts met the recommendations for the title, participant eligibility criteria, primary outcome, randomization technique, blinding, numbers analyzed, primary outcome results, and harms to participants. The number of items reported was higher in abstracts of RCTs that included clinical patients (vs other participants; OR, 1.13; 95% CI, 1.05 to 1.22). The number of items reported did not significantly change over time. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that the reporting quality of abstracts of RCTs in general veterinary journals was suboptimal per CONSORT recommendations. Because abstracts may be the only reference material available in certain settings, improvements are warranted to ensure readers have the information they need to properly interpret reported findings.

Abstract
OBJECTIVES To assess and compare the reporting quality of systematic review (SR) abstracts in operative dentistry published before and after the release of Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Abstracts (PRISMA-A), and to identify factors associated with reporting quality. METHODS PubMed was searched for abstracts published during 2010-2012 (Pre-PRISMA period) and 2017-2019 (Post-PRISMA period). Reporting quality was assessed and scored using a modified 13-item PRSIMA-A checklist. Risk ratio (RR) was used to compare the adequate reporting rate of each item between the two periods. Univariable and multivariable linear regression analyses were performed to identify factors associated with reporting quality. RESULTS A total of 160 abstracts were included and assessed. Only four items ('objective', 'results of main outcomes', 'description of the effect' and 'interpretation') were adequately reported in most abstracts (>75 %). According to the multivariable analysis, greater word count (P = 0.001), being published in the Post-PRISMA period (P = 0.025) and geographic origin from Asia (P = 0.025) or South America (P = 0.015) were significantly associated with higher reporting quality. CONCLUSIONS/CLINICAL SIGNIFICANCE The reporting quality of SR abstracts in operative dentistry had improved significantly after the publication of PRISMA-A, but was still suboptimal. Researchers, reviewers and journal editors in operative dentistry need to be familiar with the PRISMA-A checklist, and make concerted efforts to improve the reporting of SR abstracts.

Abstract
OBJECTIVES To investigate the full publication proportion (FPP) of abstracts presented at the 2010 and 2011 EAO Congresses, analyse the discrepancies between abstracts and their full publications, and explore potential predictors of FPP and discrepancies. METHODS Abstracts presented at the 2010 and 2011 EAO Congresses were retrieved. Associated full publications were identified by searching PubMed, Embase and Google Scholar. Discrepancies between abstracts and full publications were identified, classified and evaluated using a discrepancy score. The Kaplan-Meier survival analysis was used to describe cumulative FPP over time. Predictors for FPP and the discrepancy score were analysed using cox regression modelling and a linear regression model, respectively. RESULTS 850 abstracts were included. The overall FPP was 36.4% with a median time lapse of 12 months. Higher FPP were significantly associated with oral presentation (HR=2.33; 95% CI: 1.68 to 3.22; p<0.001), multiple affiliations (HR =1.32; 95% CI: 1.00 to 1.73; p=0.048) and presence of statistical tests (HR =1.78; 95% CI: 1.36 to 2.32; p<0.001). 91.3% pairs had at least one minor change from the abstract and 70.9% had at least one major change. Greater discrepancy score was significantly associated with longer time lapse (B=0.06; 95% CI: 0.04 to 0.08; p<0.001) and being clinical research (B=1.30; 95% CI: 0.52 to 2.08; p=0.001). CONCLUSIONS Thirty-six percent of abstracts presented at the EAO Congresses were published. Among these, more than two-thirds showed at least one major change in their full publications. Abstracts presented in oral implantology conferences should not be relied upon to inform practice.

Abstract
AIMS To assess the reporting quality of recently published randomised controlled trial (RCT) abstracts in Endodontics, to investigate factors associated with reporting quality, and to evaluate the existence and characteristics of spin. Spin refers to reporting strategies that distort study results and misguide readers. METHODOLOGY The PubMed database was searched to identify abstracts of RCTs in the field of Endodontics published during 2017 to 2018. Two authors assessed the reporting quality of each included abstract using the original 16-item CONSORT for Abstracts checklist, with the overall quality score (OQS, range: 0 to 16) being the primary outcome measure. For each individual item, a score of '1' was given if it was described adequately, and '0' if the description was inadequate. Linear regression analyses were conducted to identify factors associated with reporting quality. For the evaluation of spin, two authors selected parallel-group RCTs with a nonsignificant primary outcome from the included abstracts, and evaluated independently the existence and characteristics of spin among these abstracts. RESULTS A total of 162 abstracts were included for assessment of reporting, for which the mean OQS was 3.97 (SD, 1.30; 95 % CI, 3.77 to 4.17). According to multivariable analysis, origin from Europe (P=0.001) and reporting of the exact P value (P=0.020) were significantly associated with better reporting. Forty abstracts with statistically nonsignificant results for their primary outcome were included for spin evaluation, among which 34 (85.0%) had at least one type of spin. Thirty-two abstracts (94.1%) had spin in their conclusions section, and six abstracts (17.6%) had spin in the results section. CONCLUSIONS The reporting quality of RCT abstracts in Endodontics needs to be improved. The occurrence rate of spin in the sample of abstracts of RCTs in the field of Endodontics was high. Relevant stakeholders are recommended to be familiar with the CONSORT for Abstracts guideline and develop active strategies to ensure its implementation.

Abstract
OBJECTIVES To evaluate the reporting quality of randomised controlled trial (RCT) abstracts presented at a leading international conference in sleep medicine (the SLEEP Annual Meeting), and to investigate the association between potential predictors and the reporting quality of trial abstracts in this field. DESIGN Cross-sectional, research on research study. METHODS A handsearch of the 2016-2018 SLEEP Annual Meeting abstract books was carried out to identify abstracts describing RCTs. Quality of reporting was assessed with the original 17-item CONSORT for Abstracts checklist. Univariable and multivariable linear regression analyses were performed to identify significant predictors of reporting quality. In addition, risk ratios were used to analyse the adequate reporting rate of each quality item by type of intervention and funding status. PRIMARY AND SECONDARY OUTCOME MEASURES The overall quality score (OQS, range 0-17) in accordance with the CONSORT for Abstracts checklist (primary outcome), and the adequate reporting rate of each checklist item (secondary outcome). RESULTS A total of 176 RCT abstracts were included and assessed. The mean OQS was 5.53 (95% CI 5.30 to 5.76). Only three quality items (objective, conclusions and funding) were adequately reported in most abstracts (>75%). None of the abstracts adequately reported authors, randomisation or outcome in the results section. According to the multivariable analysis, pharmacological interventions (p=0.018) and funding from the industry (p=0.025) were significantly associated with better reporting quality. CONCLUSIONS The reporting quality of RCT abstracts presented at SLEEP Annual Meetings was suboptimal. Pharmacological intervention and funding from industry were significant predictors of better reporting quality. Joint efforts by authors and conference committees are needed to enhance the reporting quality of RCT abstracts presented at sleep medicine conferences, and thereby reduce relevant research waste in this field.

Reporting quality of randomised controlled trial abstracts on age-related macular degeneration health care: a cross-sectional quantification of the adherence to CONSORT abstract reporting recommendations. BMJ Open 2018; 8:e021912. [PMID: 29789352 PMCID: PMC5988143 DOI: 10.1136/bmjopen-2018-021912] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2018] [Revised: 03/12/2018] [Accepted: 04/18/2018] [Indexed: 12/20/2022] Open
Abstract
OBJECTIVE To assess the reporting quality of randomised controlled trial (RCT) abstracts on age-related macular degeneration (AMD) healthcare, to evaluate the adherence to the Consolidated Standards of Reporting Trials (CONSORT) statement's recommendations on minimum abstract information and to identify journal characteristics associated with abstract reporting quality. DESIGN Cross-sectional evaluation of RCT abstracts on AMD healthcare. METHODS A PubMed search was implemented to identify RCT abstracts on AMD healthcare published in the English language between January 2004 and December 2013. Data extraction was performed by two parallel readers independently by means of a documentation format in accordance with the 16 items of the CONSORT checklist for abstracts. The total number of criteria fulfilled by an abstract was derived as primary endpoint of the investigation; incidence rate ratios (IRRs) with unadjusted 95% CI were estimated by means of multiple Poisson regression to identify journal and article characteristics (publication year, multicentre design, structured abstract recommendations, effective sample size, effective abstract word counts and journal impact factor) possibly associated with the total number of fulfilled items. STUDY CHARACTERISTICS 136 of 673 identified abstracts (published in 36 different journals) fulfilled all eligibility criteria. RESULTS The median number of fulfilled items was 7 (95% CI 7 to 8). No abstract reported all 16 recommended items; the maximum total number was 14, the minimum 3 of 16 items. Multivariate analysis only demonstrated the abstracts' word counts as being significantly associated with a better reporting of abstracts (Poisson regression-based IRR 1.002, 95% CI 1.001 to 1.003). CONCLUSIONS Reporting quality of RCT abstracts on AMD investigations showed a considerable potential for improvement to meet the CONSORT abstract reporting recommendations. Furthermore, word counts of abstracts were identified as significantly associated with the overall abstract reporting quality.

BMC Med Res Methodol 2018; 18:6. [PMID: 29316880 PMCID: PMC5761197 DOI: 10.1186/s12874-017-0469-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2017] [Accepted: 12/28/2017] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND The reporting of randomised controlled trial (RCT) abstracts is of vital importance. The primary objective of this study was to investigate the association between structure format and RCT abstracts' quality of methodology reporting, informed by the current requirement and usage of structure formats by leading general medical/internal medicine journals (secondary objective). METHODS A two-part cross-sectional study. First, through hand searches, we identified all RCTs published in the top-50 high-impact general medical/internal medicine journals during July-December 2015 (n = 370), and retrieved the 'instructions to authors' of these journals. From these, we extracted the actual usage of structure formats and headings, as well as relevant journal policies. Then, after a pilot study and sample size calculation, we assessed the methodology reporting quality of 176 IMRaD (Introduction, Methods, Results, and Discussion) and 165 HS (Highly Structured) RCT abstracts sampled from 33 of the 50 selected journals, using a 9-item checklist developed based on the CONSORT for Abstracts guidelines (primary outcome: overall quality score, OQS; score range 0 to 9). RESULTS 88% (324/370) of all identified RCT abstracts were structured, among which 66% (215/324) used the IMRaD format and 34% (109/324) used HS. According to journals' 'instructions to authors', 48% (24/50) journals required IMRaD, 32% (16/50) required HS, 8% (4/50) required unstructured, while the rest did not state any requirement on structure format. According to generalised estimation equation analysis adjusting for potential confounders and clustering effects, the OQS of HS abstracts was 0.5 (95% CI 0.1 to 1.0, p = 0.028) higher than IMRaD abstracts. More HS abstracts reported study setting (adjusted odds ratio, 4.2; 95% CI: 1.7 to 10.0; p = 0.001), definition of the main outcome measure (2.5; 1.3 to 4.9; p = 0.006) and the time point for main outcome assessment (3.0; 1.5 to 6.2; p = 0.002), whereas more IMRaD abstracts described the unit of randomisation (0.4; 0.3 to 0.8; p = 0.004). CONCLUSIONS For RCT abstracts, the IMRaD format is more frequently used and required by leading general medical/internal medicine journals than the HS format. Abstracts in the HS format report trial methodology more completely than those in the IMRaD format.

Abstract
The objectives of this study were to assess the reporting quality of randomized controlled trial (RCT) abstracts published in leading laser medicine journals and investigate the association between potential predictors and reporting quality. The official online archives of four leading laser medicine journals were hand-searched to identify RCTs published in 2014 and 2015. A reporting quality assessment was carried out using the original 16-item CONsolidated Standards Of Reporting Trials (CONSORT) for Abstracts checklist. For each abstract, an overall CONSORT score (OCS) was calculated (score range, 0 to 16). Univariable and multivariable linear regression analyses were performed to identify significant predictors of reporting quality. Chi-square (or Fisher's exact) tests were used to analyze the adequate reporting rate of each quality item by specialty area. A total of 129 RCT abstracts were included and assessed. The mean OCS was 4.5 (standard deviation, 1.3). Only three quality items (interventions, objective, conclusions) were reported adequately in most abstracts (>80 %). No abstract adequately reported results for the primary outcome, source of funding, and status of the trial. In addition, sufficient reporting of participants, outcome in the methods section, randomization, and trial registration was rare (<5 %). According to multivariable linear regression analysis, the specialty area of RCT abstracts was significantly associated with their reporting quality (P = 0.008). The reporting quality of RCT abstracts published in leading laser medicine journals is suboptimal. Joint efforts by authors, editors, and other stakeholders in the field to improve trial abstract reporting are needed.
