Mean ± SD for continuous variables: the value was calculated by the weighted linear regression model. Percentage (%) for categorical variables: the value was calculated by the weighted chi-square test. HbA1c, glycosylated hemoglobin; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; TG, triglyceride; TCHO, total cholesterol; SBP, systolic blood pressure; DBP, diastolic blood pressure.
