  1. Data are hazard ratio (95% CI); proportional hazard Cox regression was used. HR, Hazard Ratio; CI, Confidence Interval; CVD, Cardio-vascular Disease
  2. Model 1 was adjusted for sex, waist circumference, body mass index, CVD score, hypertension and physical activity. Model 2 was additionally adjusted for total energy intake (kcal/d), total fat (g/d), total fiber (g/d), cholesterol (mg/d), tea and coffee intake (ml/d)
