Fig. 5From: A prospective study of dietary and supplemental zinc intake and risk of type 2 diabetes depending on genetic variation in SLC30A8 Tertiles of zinc to iron ratio and risk of T2D across SLC30A8 rs13266634 genotype among obese subjects in the MDCS (n = 2550). Hazard ratios (HR) from a Cox proportional hazards model adjusting for dietary and non-dietary confounders. P three-way interaction (zinc to iron ratio × BMI × genotype) = 0.007Back to article page
