VDR and hypertensive disorder: Another study carried out in a Caucasian population (United States) (205 cases/206 controls) also evaluated the influence of the VDR FokI polymorphism on the risk of congestive heart failure (HF) in patients with hypertension, without finding any statistically significant association in any of the analyzed models [(p > 0.05 OR = 0.82; 95% CI = 0.47–1.42; TC vs. CC); (p > 0.05; OR = 0.85; 95% CI = 0.39–1.88; TT vs. CC); (p > 0.05; OR = 0.82; 95% CI = 0.49–1.39; CT + TT vs. CC)] [53].
