  1. Data are given as the mean ± SD or median (IQ 25–75) unless otherwise indicated
  2. Metabolic syndrome was defined as 3 or more of the following: TGs ≥ 110 mg/dl; HDL-C < 40 mg/dl; FPG ≥ 100 mg/dl; WC ≥ 90th percentile for age and sex, according to national reference curves [16]; and SBP and/or DBP ≥ 90th percentile for sex, age, and height, according to the National Heart, Lung, and Blood Institute’s recommended cut-off points [17]
  3. WC waist circumference, SBP systolic blood pressure, DBP diastolic blood pressure, HDL-C high-density lipoprotein cholesterol, TGs triglycerides, FPG fasting plasma glucose
