  1. RDW red blood cell distribution width
  2. Metabolic syndrome diagnosed when at least three of the followings criteria were met: (1) Waist ≥90 cm in men, ≥ 80 cm in women, (2) TG ≥ 1.70 mol/L, (3) HDL < 1.03 mmol/L in men, < 1.29 mmol/L in women, (4) SBP ≥ 130 mmHg or DBP ≥ 85 mmHg, and (5) FG ≥ 5.60 mmol/L.
  3. * P < 0.05, ** P < 0.01 (analyzed by Chi-square test)
