Association of plasma Vitamin D metabolites with incident type 2 diabetes : EPIC-InterAct case-cohort study
Background: Existing evidence for the prospective association of vitamin D status with type 2 diabetes (T2D) is focused almost exclusively on circulating total 25-hydroxyvitamin D [25(OH)D] without distinction between its subtypes: Nonepimeric and epimeric 25(OH)D 3 stereoisomers, and 25(OH)D 2 , the minor component of 25(OH)D. We aimed to investigate the prospective associations of circulating
