Meta-analysis of association studies on VDR TaqI polymorphism vs. risk for renal disease. Forest plot: The terms experimental and control groups corresponds to cases and controls. Number of variant alleles was considered as events with respect to total number of alleles tested. This meta-analysis was based on 16 case-control studies representing seven population groups. VDR TaqI polymorphism was shown to exert risk for renal disease both in fixed effect and random effect models. Funnel Diagram: It is depicting that no heterogeneity in association. Sensitivity analysis: Exclusion of any of the study is not influencing the result
