Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.展开更多

Methods: Proportions of studies that reported CONSORT and STRICTA items were compared for the years before and after implementation of these two guidelines. In addition, the total score of each item's reporting were calculated and reported differences during different date ranges were compared. Results: For CONSORT items (maximum score 8), there was evidence of a slight improvement in reporting between 1994-1995 and 1999-2000 combined (2.5 ± 0.6) and 2004-2006 and 2009-2010 combined (3.0 ± 0.9; difference 0.4, 95% confidence interval, 0.3 to 0.6, P〈0.01). For STRICTA items (maximum score 17), there was evidence that a slight improvement in reporting between 1994-1995 and 1999-2000 combined (8.6±2.1) and 2004-2005 and 2009-2010 combined (10.1 ±1.8; difference 1.5, 95% confidence interval, 1.1 to 1.9, P〈0.01). Conclusion: Quality of reporting for RCTs of acupuncture treatment conducted in China have generally improved since the introduction of the STRICTA and CONSORT guidelines.展开更多

Although the name of a Kampo manufacturer was described in 77.9% of research articles, the name and ratios of crude drug components of Kampo formulas were not described in 77.5% of these papers. Considering the importance of proper characterization of interventions in the Consolidated Standards of Reporting Trials (CONSORT) checklist, we hereby propose the use of the Standards of Reporting Kampo Products (STORK) website, http://mpdb.nibiohn.go.jp/stork, as a reference for Kampo products. This will provide an official source on the internet for verified information on individual Kampo formulations for citation purposes in clinical research articles.展开更多

Methods: We reviewed the latest "instruction to authors" of the CM journals in China which indexed by MEDLINE in 2010 or Excerpta Medica Database (EMBASE) in 2012 and extracted all information of CONSORT, International Committee of Medical Journal Editors (ICMJE), other reporting guidelines or clinical trial registration. By reading the instructions to authors and reviewing recent studies published in those journals, those that do not publish clinical trials were excluded. We also contacted each of journals by telephone on contributor's status to ask them whether mentioned CONSORT in their instructions and incorporated it into their editorial and peer-review process. Full-text papers of randomized controlled trials (RCTs, from January 2011 to March 2012) published in the journals which mentioned "CONSORT" in their instructions for authors were downloaded. Results: Seven CM journals were included. Three of these journals mentioned CONSORT in its instructions. By telephone survey, all journals gave responses and all respondents knew CONSORT statement. Three of 7 journals required authors to comply with the CONSORT statement and provide the CONSORT checklist and a flow chart of the trial. The rest 4 journals recommended authors of RCTs to refer to the CONSORT statement. From January 2011 to March 2012, a total of 50 RCTs were obtained from the 3 journals endorsing the CONSORT statement; 17 (17/50, 34%) contained a flow diagram in their manuscript, and none of those RCTs had mentioned the trial registration information. Conclusions: The endorsement of CONSORT by CM journals' "instruction to authors" was not satisfactory. The spread of CONSORT endorsement should be wider in instructing the performance of CM clinical trials in the future. Chinese journals should introduce CONSORT to their authors and require authors to comply with CONSORT when they submit their research.展开更多
