  1. Values indicate the weighted mean ± SD or weighted median (95% CI) or weighted % (95% CI). The results are weighted based on the survey.
  2. BMI body mass index, SBP systolic blood pressure, DBP diastole blood pressure, TC total cholesterol, TG triglyceride, HDL-C high-density lipoprotein cholesterol, CMI cardiometabolic index, CVD cardiovascular disease, CKD chronic kidney disease.
  3. P values are weighted.
