Methods We searched the Cochrane Central Register of Controlled Clinical Trials (CENTRAL) (The Cochrane Library , Issue 4 , 2006) , PubMed , EMbase , the Chinese Biomedical Database (CBMdisc) , VIP Information , and China National Knowledge Infrastructure (CNKI) (from establishment to February 2007). We also checked the reference lists of included studies. The quality of the reporting of RCTs was assessed using the 22-item checklist of the CONSORT Statement and other self-established criteria. Results Thirty-eight RCTs were included. The word “randomization” was not present in any of the trials , and only 17 reports used a structured abstract. All trials did not report the scientific background and the rational for the trial , the estimation of the necessary sample size , the methods of allocation concealment and blinding , participant flow chart , ITT analysis , and ancillary analyses. Some authors misunderstood the diagnostic criteria and inclusion criteria , some selected inappropriate control interventions , and some did not clearly describe their statistical methods or used incorrect methods. All 38 trials reported positive outcomes , few reported adverse effects. No report included a general interpretation of the new trial’s results in the context of current evidence in their discussion section , and none mentioned the limitations of the study , the clinical and research implications or the external validity of the trial findings. Conclusion The overall reporting quality of RCTs of TCM for CFS is poor. Defects are found in each section of the reports. Researchers and journal editors should learn and use the principles and methods of evidence-based medicine—especially the use of a transparent prospective cl inical trial register and the CONSORT Statement—to improve the design , conduct and report TCM trials.Read More
