  1. Crude model: we did not adjust other covariates.
  2. Model I: we adjusted age, sex.
  3. Model II: we adjusted age, sex, BMI, ALT, AST, BUN, Scr, TG, LDL-c, HDL-c, family history of diabetes, drinking status, and smoking status.
  4. Model III: we adjusted age (smooth), sex, BMI (smooth), Scr (smooth), TG (smooth), ALT (smooth), AST (smooth), LDL-c (smooth), HDL-c (smooth), smoking status, drinking status, family history of diabetes. HR, Hazard ratios; CI, confidence, Ref, reference.
