Data are expressed as mean (SD), median (25% quantile, 75% quantile), or count (percentage) depending on the variable type. The value was calculated by independent two-sample t-tests, Mann–Whitney U test, or chi-square test accordingly.When , when , and when . BMI: body mass index; FPG: fasting plasma glucose; SBP: systolic blood pressure; DBP: diastolic blood pressure; TC: total cholesterol; TG: triglycerides; LDL-C: low-density lipoprotein cholesterol; and HDL-C: high-density lipoprotein cholesterol.
