ALT/HDL-C ratio: alanine aminotransferase to high-density lipoprotein cholesterol ratio; SD: standard deviation; NAFLD: non-alcoholic fatty liver disease.

Model 1 adjusted for age, sex, height and BMI;

Model 2 adjusted for age, sex, height, BMI, exercise habits, smoking status and drinking status;

Model 3 adjusted for age, sex, height, BMI, exercise habits, smoking status, drinking status, AST, GGT, TC, TG, FPG, HbA1c and SBP.

In the analysis of AST/HDL-C ratio and GGT/HDL-C ratio and NAFLD in Model 3, the variables themselves were not adjusted.
