  1. 1Data are β regression and 95% confidence interval were estimated by using multiple regression models with adjustment for sex, age at baseline (y, continuous), BMI (kg/m2, continuous), education (4 categories), smoking (yes or no), physical activity (MET-h/wk, continuous), total energy intake (kcal/d), dietary carbohydrate (% of energy), fat (% of energy) and protein (% of energy).
  2. 2A linear trend test was performed by considering each ordinal score variable as a continuous variable in the model.
