  1. Data are shown in mean ± standard deviations. P values were obtained from t test. P for trend was obtained by one-way ANOVA
  2. All biomarkers detected were fasting
  3. a Waist circumference ≥ 85 cm in men and ≥ 80 cm in women. b Triglyceridemia ≥150 mg/dL. c HDL cholesterol < 40 mg/dL in men and < 50 mg/dL in women. d Blood pressure ≥ 130/85 mmHg and/or use of antihypertensive medication. e Fasting blood glucose ≥100 mg/dL and/or current use of antidiabetic medication and/or self-reported history of diabetes
