Model 1, adjusted for age, sex, systolic and diastolic blood pressure, and iPTH; Model 2, adjusted for age, sex, systolic and diastolic blood pressure, iPTH, and ALP. Model 3, adjusted for age, sex, systolic and diastolic blood pressure, iPTH, ALP, and antiplatelets. Aspirin and clopidogrel are combined as one confounder as antiplatelets. OR = odds ratios; 95% CI = 95% confidence interval; BP, blood pressure; IPTH, Intact parathyroid hormone; ALP, alkaline phosphatase.
