title: [Evaluation on quality of large sample clinical trials of acupuncture in foreign countries].
abstract: Following retrieving articles about foreign large sample clinical trials of acupuncture (more than 500 cases) from MEDLINE and EMBASE databases (1996-2012) by using keywords of "acupuncture" and "clinical trial", a quality analysis was carried out independently by two researchers. A total of 1373 papers were collected and 37 were considered to meet our preformulated standards in accordance with the principles and methods of evidence-based medicine. Majority of these 37 articles were from some advanced countries including Germany, USA, Japan, Demark, Australia, et al. Their paper quality and research quality are varied including the methodology, standards for diagnosis, inclusive and exclusive criteria, follow-up survey, economic effectiveness, adverse effects, acupoint application and syndrome differentiation of traditional Chinese medicine. Of the 37 papers, 17 are multiple center clinical trials, 18 are one center clinical trials, and 2 are not clear. Our Chinese researchers should pay more attention to foreign well-designed, large example, randomized controlled clinical trials and draw their matured experience and strong points to compensate our weak points and to improve our levels in clinical study on acupuncture treatment of clinical disorders.
