Model 1: adjusted for age. Model 2: model 1 plus systolic blood pressure, body mass index, total cholesterol, triglycerides, smoking status, a history of type 2 diabetes, a history of coronary heart disease, medication for dyslipidemia, alcohol consumption, physical activity, socioeconomic status, and serum active calcium. Model 3: model 2 plus high-sensitivity C-reactive protein and a history of cancer. CI, confidence interval; HR, hazard ratio; ref., reference; SD, standard deviation; T, tertile.
