It has also been suggested that half the literatures published is redundant as it is never cited.2 Therefore, many non-cited articles are published in scientific journals. In this article, the distribution of non-cited articles published in the Chinese Medical Journal （C34.1） in 2010 is reported aiming to provide evidence to guide the editorial work.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 By reading the instructions to authors and reviewing recent studies published in those journals, those that do not publish clinical trials were excluded.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

Chinese Medical Journal （CMJ） is a leading platform in China for following the progress of medical research in various disciplines from China and any part of the world. As an international, peer-reviewed general medical journal from the Chinese Medical Association, impact factor （IF） of CMJ increased to 1.016 in 2013 （Thomson Reuters, USA）.展开更多
