Efficacy of clomifene citrate combined Bushen Culuan Decoction for the treatment of infertility caused by polycystic ovary syndrome: A protocol of systematic review

BACKGROUND: The aim of this study is to assess the efficacy and safety of clomifene citrate combined Bushen Culuan Decoction (CCBCD) in treating infertility caused by polycystic ovary syndrome (PCOS). METHODS: We will carry out this study to identify eligible randomized controlled trials (RCTs) in Cochrane Library, PUBMED, EMBASE, Web of Science, CINAHL, and China National Knowledge Infrastructure from inception to the present. There are no limitations to the language and publication time. We will perform study selection, data extraction, and study quality assessment. If possible, a meta-analysis will be developed to judge the comparative efficacy and safety of CCBCD with other treatments. RESULTS: The results of this study will summarize current high quality RCTs to provide direct evidence of CCBCD in treating infertility in patients with PCOS. CONCLUSION: This study may provide evidence to determine whether CCBCD is effective and safe or not for the treatment of infertility caused by PCOS. STUDY REGISTRATION: INPLASY202050090.
