  1. BMI, body mass index; FPG, fasting plasma glucose; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; TG, triglycerides
  2. I: Adjustments were made for gender, age, education, smoking status, alcohol intake, regular exercise, residence and job type
  3. II: Model I along with hypertension, BMI, consumptions of staple foods and eggs
  4. III: Model II along with LDL-C, TG, antihypertensive drug and cardiovascular medication
