Intradermal acupuncture for primary dysmenorrhea: A protocol of systematic review and meta-analysis of randomized clinical trials

BACKGROUND: Primary dysmenorrhea (PD) is one of the common gynecological diseases, the incidence of PD is on the rise and young women are more likely to have it, which seriously affects women's physical, mental health and work life. Intradermal acupuncture is effective in treating PD. However, due to the lack of evidence, there is no specific method or suggestion, so it is necessary to carry out systematic evaluation on intradermal acupuncture and provide effective evidence for further research. METHODS: We will search the following electronic databases from their inception to July 2020: Electronic database includes PubMed, Embase, Cochrane Library, Chinese Biomedical Database WangFang, VIP medicine information, and CNKI (China National Knowledge Infrastructure). Primary outcomes: the overall effective rate, VAS score. Secondary outcomes: blood serum estradiol (E2), progesterone (P), prostaglandin F2α (PGF-2α), adverse events Data will be extracted by 2 researchers independently, risk of bias of the meta-analysis will be evaluated based on the Cochrane Handbook for Systematic Reviews of Interventions. All data analysis will be conducted by data statistics software Review Manager V.5.3. and Stata V.12.0. RESULTS: The results of this study will systematically evaluate the effectiveness and safety of intradermal acupuncture in the treatment of primary dysmenorrhea. CONCLUSION: The systematic review of this study will summarize the currently published evidence of intradermal acupuncture therapy for primary dysmenorrhea to further guide its promotion and application.
