  1. Note: To convert serum cholesterol in mmol/L to mg/dL, multiply by 38.67; serum triglycerides in mmol/L to mg/dL, multiply by 88.545; serum creatinine in mg/dL to μmol/L, multiply by 88.4; serum uric acid in μmol/L to mg/dL, multiply by 0.01681. Central obesity was defined as a waist measurement greater than 90 cm for men or greater than 80 cm for women; Hypercholesterolemia was defined as total cholesterol greater than 240 mg/dL; Hypertriglyceridemia was defined as triglycerides greater than 150 mg/dL.
  2. Abbreviations: SBP, systolic blood pressure; DBP, diastolic blood pressure; PP, pulse pressure; BMI, body mass index; HDL, high-desity lipoprotein; eGFR, estimated glomerular filtration rate; ACR, albumin-creatinine ratio; IQR, interquartile range; IMT, intima-media thickness.
