  1. Values are expressed as means ± standard deviations except IRI, TG, and free fatty acids which are given as the medians and the interquartile ranges in parentheses
  2. *P < 0.05 is considered to indicate statistically significant differences between men and women. The Mann-Whitney nonparametric test was used for the differences of IRI, TG and free fatty acids. The other continuous variables were estimated by Student’s t-test
  3. BMI body mass index, SBP systolic blood pressure, DBP diastolic blood pressure, HbA1c glycosylated hemoglobin A1c, IRI immunoreactive insulin, TC total cholesterol, HDL-C high-density lipoprotein-cholesterol, TG triglyceride, LCAT lecithin cholesterol acyltransferase
