Abstract：Objective：To evaluate the clinical effect of 6 acupuncture and moxibustion therapies on primary dysmenorrhea (PD) and their safety based on Bayesian Meta-analysis. Methods：Using computers to search databases， including PubMed and Web of science， the research literature on randomized controlledtrialsofsixcommonacupuncturetherapies(needling，acupunctureandmoxibustion，moxibustion， warming-needle moxibustion，electroacupuncture and acupoint catgut embedment) for PD were collected from 1 st January，2000 to 30 th September，2020. Two investigators independently screened the literature， extracted data and evaluated the risk of bias in the included studies. R software was used for data analysis and the network chart was made with Stata 16.0 software. Results：A total of 98 studies on randomized controlled trial involving 7 410 patients with PD and 8 intervention measures. All outcome indicators suggested that the overall goodness-of-fit of random effect model was good and network Meta-analysis can be done under the consistency model. In terms of effective rate， single needling， moxibustion， acupuncture and moxibustion， warming- needle moxibustion， electroacupuncture and acupoint catgut embedment were better than blank control or placebo and non-steroidal anti-inflammatory drugs，and acupuncture and moxibustion， and warming- needle moxibustion were better than single needling and single moxibustion，with warming-needle moxibustion coming first. As for pain relief，acupuncture was superior to single acupuncture and single moxibustion， and all intervention measures except for moxibustion and electroacupuncture were better than non- steroidal anti- inflammatory drugs， with acupuncture ranking first. There was no significant difference being found in the comparison of safety between the intervention measures，and they all showed good safety. Conclusion：The clinical effects of the six acupuncture and moxibustion therapies for PD are superior to those of non- steroidal anti- inflammatory drugs，acupuncture and moxibustion，and warming-needle moxibustion can often be the therapies of choice for PD.
