The incidence cases, follow-up person-years, and the rates of cardiovascular disease events and all-cause deaths, and the hazard ratios and 95% confidence intervals of 25(OH)D concentrations in the study participants, according to quartiles.

Abbreviation: HR, hazard ratio; CI, confidence interval; CVD, cardiovascular disease; py, person year; Model 1: adjusted for age and gender, Model 2: Model 1 & additionally adjusted for body mass index, smoking, drinking, marital status, education level, job, and sports activity, Model 3: Model 2 & additionally adjusted for hypertension, diabetes, LDL cholesterol and HDL cholesterol level, Cox proportional hazards model was applied for estimating the relative risks and 95% confidence intervals The incidence cases, follow-up person-years, and the rates of cardiovascular disease events and all-cause deaths, and the hazard ratios and 95% confidence intervals of 25(OH)D concentrations in the study participants, according to quartiles.
