  1. Model I was non adjusted. Model II was adjusted for age and sex. Model III was adjusted for age, sex, smoking, drinking, physical activity, SBP, DBP, antihypertensive, hypoglycemic, and hypolipidemic medication use, duration of diabetes, HbA1c, FPG, 2hPG, ALT, AST, TG, HDL-C, TC, LDL-C, ABI, CR, and eGFR.
  2. AS, arterial stiffness; BMI, body mass index; WC, waist circumference; WWI, weight-adjusted waist index; ABSI, a body shape index; BRI, body round index; OR, odds ratio; CI, confidence interval.
