  1. Model 1 was crude
  2. Model 2 was adjusted for age, gender, smoking, physical activity, education levels, occupation status, total energy intake, and family history of diabetes, dietary fiber and dietary cholesterol (all variable that adjusted was at baseline)
  3. Model 3 was additionally adjusted for BMI at baseline
