  1. HOMA-IR homeostasis model assessment of insulin resistance, BMI body mass index, WC waist circumference, SBP systolic blood pressure, DBP diastolic blood pressure, FPG fasting plasma glucose
  2. Data are shown as mean (standard deviation)
  3. a P values for difference across all quartiles of HOMA-IR changes were calculated with ANOVA test
