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 By reading the instructions to authors and reviewing recent studies published in those journals, those that do not publish clinical trials were excluded.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

文摘背景:对于与随机对照试验(randomized controlled trial,RCT)有关的学术会议论文或期刊中发表的文章来说,清楚、明了、信息量充足的摘要是十分重要的,因为读者经常仅仅根据报告的摘要对一个临床试验作出评价。为此,我们需要对"临床试验报告的统一标准(Consolidated Standards of Reporting Trials,CONSORT)声明"进行扩充,制定一个期刊与学术会议论文摘要中报告RCT的必备条目清单。今后在任何期刊发表的论文或学术会议论文摘要中,作者对RCT结果的报告都要包含这些内容。方法与结果:我们根据现有的质量评价工具和基于经验的证据总结出一个条目清单。运用三轮修正式德尔菲法(modified-Delphi process)进行条目筛选。邀请共计109人参与电子网络调查,反馈率为61%。调查结果于2007年1月在加拿大蒙特贝罗举行的CONSORT小组会议中公布,与会的26人中有临床试验实施人员、统计学家、流行病学家以及生物医学编辑。经过讨论最终确定条目,随后对其进行修订以保证这些条目体现了会议期间以及会后的讨论思路。摘要CONSORT建议RCT报告的摘要需要有一个结构化的格式,其中应该包括具体的试验目的、试验设计(随机分配的方法、盲法或遮蔽等)、研究对象(对象描述、随机分组的样本量以及用于分析的样本量)、每组实施的干预、实施的干预对主要疗效结果的影响及其危害、试验结论、试验注册名称和编号以及资金来源。本文对每一条能够找到例子的纳入条目都配有良好报告范例、基本原理以及证据等,十分明了易懂,因此我们建议与清单同时使用。结论:摘要CONSORT旨在改善期刊与学术会议中发表的论文摘要的质量,这将有助于摘要提供详尽清晰的信息,这些信息能够帮助读者对试验的有效性和试验结果的适用性做出正确的评价。
