According to the outcomes of our meta-analysis, 3 of 4 VDR polymorphisms (Fok-1, Bsm-1, Apa-1) were not associated with the BPH risk in overall populations, which were similar to the results of prior meta-analysis.[9] Our meta-analysis omitted a cohort study by Mullan et al,[27] which included the Taq-1 and Bsm-1 polymorphisms because its Newcastle Ottawa Scale was <5 points. This evidence concerns the gene VDR and benign prostatic hyperplasia.
