Abstract
OBJECTIVE To determine abstracts' adherence to the Consolidated Standards of Reporting Trials for Abstracts (CONSORT-A) statement and to explore the factors associated with reporting quality. DESIGN An observational study. SETTING Abstracts of randomised controlled trials published between 2010 and 2019, found searching the MEDLINE database. PARTICIPANTS A total of 451 abstracts of the clinical trials on Helicobacter pylori infections were included. PRIMARY AND SECONDARY OUTCOME MEASURES Abstracts' reporting quality was determined by assessing their adherence to 17-item CONSORT-A checklist, with overall score being calculated as the sum of items that were adequately reported for each abstract. Additional factors that might influence the reporting quality of the abstracts were analysed, with univariate and multivariate linear regression used to determine how those factors influenced the overall reporting quality. RESULTS Included abstracts had an overall median quality score of 8/17 (IQR 7-9). Large proportions of abstracts adequately reported interventions, participants, objectives, numbers randomised and conclusions (97.1, 99.3, 89.1. 94.7 and 98.4% of abstracts, respectively). Trial design, randomisation, blinding and funding were severely under-reported with only 8.0, 2.7, 11.0 and 2.0% of abstracts reporting each item. Overall quality scores for H. pylori abstracts were higher in association with CONSORT-A endorsement (B=5.698; 95% CI 1.781 to 9.615), pharmacological interventions (B=4.063; 95% CI 0.224 to 7.902), multicentre settings (B=5.057; 95% CI 2.370 to 7.743), higher numbers of participants (B=3.607; 95% CI 1.272 to 5.942), hospital settings (B=4.827; 95% CI 1.753 to 7.901) and longer abstracts (B=3.878; 95% CI 0.787 to 6.969 for abstracts with 251-300 words and B=7.404; 95% CI 3.930 to 10.878 for abstracts with more than 300 words). CONCLUSIONS The overall reporting quality of abstracts was inadequate. The endorsement of CONSORT-A guidelines by more journals might improve the standards of reporting.

A comprehensive quality analysis of randomized controlled clinical trials of Asian ginseng and American ginseng based on the CONSORT guideline. J Ginseng Res 2022; 46:71-78. [PMID: 35035241 PMCID: PMC8753457 DOI: 10.1016/j.jgr.2021.05.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 05/05/2021] [Accepted: 05/10/2021] [Indexed: 12/21/2022] Open
Abstract
Ginseng is an international herb that has been used for thousands of years. Two species most commonly applied and investigated in the ginseng family are Asian ginseng and American ginseng. The number of randomized controlled clinical trials (RCTs) has conspicuously increased, driven by the rapid development of ginseng. However, the reporting of RCT items of ginseng is deficient because of different trial designs and reporting formats, which is a challenge for researchers who are looking for the data with high quality and reliability. Thus, this study focused on providing an extensive analysis of these two species and examined the quality of the RCTs, based on the Consolidated Standards of Reporting Trials (CONSORT) guideline. Ninety-one RCTs conducted from 1980 to 2019 that were related to Asian ginseng and American ginseng used singly met our inclusion criteria. We found that the reporting quality of the two species has improved during the past 40 years. Publication date and sample size were significantly associated with the reporting quality. Rigorous RCTs designed for the species of ginseng are warranted, which can shed light on product research and development of ginseng in the future.

Quality of reporting in abstracts of RCTs published in emergency medicine journals: a systematic survey of the literature suggests we can do better. Emerg Med J 2019; 37:660-665. [PMID: 31694858 DOI: 10.1136/emermed-2019-208629] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 07/26/2019] [Accepted: 08/02/2019] [Indexed: 12/21/2022]
Abstract
OBJECTIVE We investigated the association between the publication of the Consolidated Standards of Reporting Trials extension for abstracts (CONSORT-EA) and other variables of interest on the quality of reporting of abstracts of randomised controlled trials (RCTs) published in emergency medicine (EM) journals. METHODS We performed a survey of the literature, comparing the quality of reporting before (2005-2007) with after (2014-2015) the publication of the dedicated CONSORT-EA in 2008. The quality of reporting was measured as the sum of items of the CONSORT-EA checklist reported in each abstract, ranging from 0 to 15. The main explanatory variable was the period of publication: pre-CONSORT-EA versus post-CONSORT-EA public. Other explanatory variables were journal's endorsement of the CONSORT statement, number of centres participating in the study, study's sample size, type of intervention, significance of results, source of funding and study setting. We analysed the data using generalised estimation equations, performing a univariate and a multivariable analysis. RESULTS We retrieved 844 articles, and randomly selected 60 per period for review, after stratifying for journal. The mean (SD) number of items reported was 6.4 (1.9) in the period before and 6.9 (1.8) in the period after the publication of the CONSORT-EA, with an adjusted mean difference (aMD) of 0.47 (95% CI -0.13 to 1.06). Abstracts of trials of pharmacological interventions had a significantly larger mean number of reported items than those of trials of non-pharmacological interventions (aMD 1.59; 95% CI 0.94 to 2.24). CONCLUSIONS The quality of reporting in abstracts of RCTs published in EM journals is low and was not significantly impacted by the publication of a dedicated CONSORT-EA.

Abstract
Biological data analysis is the key to new discoveries in disease biology and drug discovery. The rapid proliferation of high-throughput ‘omics’ data has necessitated a need for tools and platforms that allow the researchers to combine and analyse different types of biological data and obtain biologically relevant knowledge. We had previously developed TargetMine, an integrative data analysis platform for target prioritisation and broad-based biological knowledge discovery. Here, we describe the newly modelled biological data types and the enhanced visual and analytical features of TargetMine. These enhancements have included: an enhanced coverage of gene–gene relations, small molecule metabolite to pathway mappings, an improved literature survey feature, and in silico prediction of gene functional associations such as protein–protein interactions and global gene co-expression. We have also described two usage examples on trans-omics data analysis and extraction of gene-disease associations using MeSH term descriptors. These examples have demonstrated how the newer enhancements in TargetMine have contributed to a more expansive coverage of the biological data space and can help interpret genotype–phenotype relations. TargetMine with its auxiliary toolkit is available at https://targetmine.mizuguchilab.org. The TargetMine source code is available at https://github.com/chenyian-nibio/targetmine-gradle.

J Dent 2018; 74:23-29. [PMID: 29742449 DOI: 10.1016/j.jdent.2018.04.025] [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] [Received: 03/08/2018] [Revised: 04/23/2018] [Accepted: 04/27/2018] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVES This study aimed to compare the reporting quality of randomized controlled trial (RCT) abstracts in prosthodontics before and after the publication of Consolidated Standards of Reporting Trials (CONSORT) guideline for abstracts and identify the characteristics associated with better reporting quality. SOURCES PubMed was searched for RCT abstracts published from 2001 to 2007 (pre-CONSORT period) and from 2010 to 2016 (post-CONSORT period) in six leading prosthodontic journals. STUDY SELECTION After applying the inclusion/exclusion criteria, 131 RCT abstracts were selected. The t test was performed to compare the overall quality between the two periods. Univariable and multivariable linear regressions were used to identify any factors relating to the reporting quality. The level of significance was set at P < 0.05. DATA The investigators extracted data and scored the abstracts independently based on CONSORT. The mean overall CONSORT score was 5.20 and 6.11 in the pre- and post-CONSORT samples, respectively. Significant changes were observed in reporting for only three items: title, conclusions, and trial registration. Most abstracts adequately reported interventions, objectives, and conclusions (>90%), but failed to report recruitment and outcome in the results section (<3%). Funding was not reported in both periods. The reporting quality was related to a higher impact factor, structured format, and published after CONSORT. CONCLUSIONS The quality of RCT abstracts in prosthodontics improved over time, but adherence to the CONSORT guideline for abstracts was still suboptimal.

Abstract
To evaluate the quality of reporting in published randomized controlled trials (RTCs) in the field of fall injuries. The 188 RTCs published between 2001 and 2011, indexed in EMBASE and Medline databases were extracted through searching by appropriate keywords and EMTree classification terms. The evaluation trustworthiness was assured through parallel evaluations of two experts in epidemiology and biostatistics. About 40%-75% of papers had problems in reporting random allocation method, allocation concealment, random allocation implementation, blinding and similarity among groups, intention to treat and balancing benefits and harms. Moreover, at least 10% of papers inappropriately/not reported the design, protocol violations, sample size justification, subgroup/adjusted analyses, presenting flow diagram, drop outs, recruitment time, baseline data, suitable effect size on outcome, ancillary analyses, limitations and generalizability. Considering the shortcomings found and due to the importance of the RCTs for fall injury prevention programmes, their reporting quality should be improved.
