Data were shown as OR (95% CI) which was evaluated using logistic regression models. Model 1: unadjusted; model 2: adjusted for age and sex; model 3: further adjusted for smoking, alcohol consumption, and history of hypertension; model 4: further adjusted for LDL-C, white blood cell count, and creatinine level; HbA1c: hemoglobin Alc; HDL-C: high-density lipoprotein cholesterol; cIMT: carotid intima-media thickness; Ref: reference; LDL-C: low-density lipoprotein cholesterol; CI: confidence interval.
