  1. BP, blood pressure; CI, confidence interval; Hb, hemoglobin; HDL-C, high-density lipoprotein cholesterol; OR, odds ratio
  2. Model 1: adjusted for age and sex
  3. Model 2: adjusted for age, sex, systolic and diastolic blood pressure, waist circumference, and the level of triglyceride, HDL-C, and fasting glucose
  4. Model 3: adjusted for age, sex, MetS, the level of creatinine, and smoking
