Background: Uterine fibroids or Leiomyoma (UFs) are one of a common problem that affects the quality of life in women. Recently use of vitamin D for treating Leiomyoma has been considered. Study's PurposeThis Systematic Review was performed with aim to evaluate the current evidence for the efficacy of vitamin D in treating uterine fibroids.Methods: Relevant studies were identified from the following Electronic searching of Medline, PubMed, Scopus, Cochrane, Embase, Web of science, SID and Google Scholar up to Feb ۲۰۲۱. Inclusion criteria consist of Both English and Persian, published, clinical trials using vitamin D as medical for treatment of uterine fibroids. In the long run four RCTs met the inclusion criteria. The quality of these trials was evaluated by two researchers who carried out the data extraction, using Oxford Center for Evidence Based Medicine checklist. Statistical analysis was performed by Comprehensive Meta-analysis (CMA) Version ۲. To assess the publication bias and heterogeneity, Egger’s and Begg’s tests and I۲ were used, respectively. In addition, the Random effects model was employed to perform the meta-analysis. Findings: The heterogeneity in the studies was determined as ۹۵.۱۷% (p<۰.۰۰۰). There was publication bias among the studies included; the p-values of Egger’s and Begg’s tests were ۰.۰۵ and ۰.۰۵, respectively. The effects of Vit D on UFs was statistically significant [mean difference (MD) =۲.۸۸; ۹۵% confidence interval (CI): (۴.۷۲-۱.۰۴۴); p<۰.۰۰۲].
