Values are presented as mean±standard deviation for continuous variables or number (%) for categorical variables.

WC, waist circumference; FBS, fasting blood sugar; TG, triglyceride; HDL, high-density lipoprotein; -, not available.

aLog substitution is performed with non-normal distribution.

P-values are from t-test for continuous variables and chi-squared test for categorical variables, respectively.
