VDR and postmenopausal osteoporosis: The results showed that VDR BsmI polymorphism was significantly associated with the risk of postmenopausal osteoporosis in Caucasian populations (additive model: OR 0.809, 95% CI 0.678~0.965, p = 0.019; recessive model: OR 0.736, 95% CI 0.568~0.955, p = 0.021; and co-dominant model: bb vs. BB OR 0.701, 95% CI 0.511~0.962, p = 0.028, Fig. 2).
