  1. aAdjusted for age (years), sex, and time.
  2. bFurther adjusted for physical activity (METs/week), postmenopausal hormone use (yes/no), multivitamin use (yes/no), alcohol consumption (non-drinker/drinker), smoking (never, past, and current).
  3. cMultivariate model additionally adjusted for dietary intakes of saturated fat (g/day), cholesterol (mg/day), glycemic load (quintiles), sodium intake (mg/day), fiber (g/day), and total energy (kcal/day).
  4. dA full model with additional adjustment for body mass index (kg/m2), history of diabetes, and family history of hypertension.
  5. eTest for linear trend.
