Fig. 3From: Association of vitamin D receptor gene rs739837 polymorphism with type 2 diabetes and gestational diabetes mellitus susceptibility: a systematic review and meta-analysisThe overall meta-analysis for the association between VDR rs739837 and T2DM or GDM susceptibility. A Allele model: T vs. G (fixed effects model). B Homozygote model: TT vs. GG (fixed effects model). C Heterozygote model: GT vs. GG (fixed effects model). D Recessive model: TT vs. GG + GT (random effects model). E Dominant model, TT + GT vs. GG (fixed effects model). OR odds ratio, CI confidence interval, I2: measurement to quantify the degree of heterogeneity in meta-analysesBack to article page
