VDR and orthostatic hypotension: Carriers of the VDR rs731236 TC genotype (OR = 0.52; 95% CI = 0.29–0.93; p = 0.028), CC genotype (OR = 0.39; 95% CI = 0.16–0.94; p = 0.035), or at least one C allele (OR = 0.49; 95% CI = 0.28–0.85; p = 0.011) had decreased odds for development of orthostatic hypotension.
