This systematic review included randomized controlled trials(RCTs) of acupuncture taking non-penetrating sham acupuncture as placebo needle. Systematic searches were conducted in 13 electronic databases up to July 2012: Medline, PubMed, the Cochrane Library, CINAHL, EMBASE, a Chinese medical database. All parallel or cross-over RCTs of acupuncture for the blinding effect of non-penetrating needle were chosen without language restrictions. Finally, totally 7 RCTs met the inclusion criteria. In conclusion, our systematic review and meta-analysis demonstrate that the non-penetrating needle is an effective instrument for placebo control in the acupuncture RCTs.展开更多
