  • Model 1: no adjustment. Model 2: adjusted for site, BMI (at baseline), race (White, Black, other). Model 3: additionally adjusted for sex and age (at baseline). Model 4: additionally adjusted for physical activity (at baseline). Model 5: additionally adjusted for statin use (at baseline). To convert the values for 25(OH)D to ng/L, divide by 2.496.
