Totally 29 articles were included. The pain was the leading disease in category of diseases; the most commonly used application of placebo acupuncture design was telescopiform sliding blunt needle, accounting for 45. 16%; the treatment locations were non-acupoints mostly; in the needling depth, approximately 60. 00% selected non-penetrating needling and 26. 67% selected superficial needling; 28 articles indicated that acupuncture and placebo acupuncture had clinical effects, accounting for 96. 55%; 37. 93% of articles indicated acupuncture was superior to placebo acupuncture and 37. 93% of articles indicated acupuncture was not superior to placebo acupuncture.
