Vitamin D levels according to BsmI (A), ApaI (B), and TaqI (C) SNPs in VDR gene grouped by presence of polymorphic allele. Values are expressed as means (central circle) and 95% CI (lower and upper limit). Two-tailed Student’s t-test, *p < 0.05 BsmI GG (n = 110) and GA + AA (n = 124); ApaI GG (n = 39) and GT + TT (n = 195); TaqI TT (n = 108) and TC + CC (n = 126).
