  1. Crude model: we did not adjust for other covariants
  2. Model I: we adjusted for age, ethanol consumption, smoking, regular exerciser, SBP, DBP, BMI, WC
  3. Model II: we adjusted for age, ethanol consumption, smoking, regular exerciser, SBP, DBP, BMI, WC, TC, TG, HbA1c, FPG
  4. GAM: All covariates listed in Table 1 were adjusted. However, continuous covariates were adjusted as nonlinearity
  5. CI Confidence interval, Ref Reference
