NAFLD, nonalcoholic fatty liver disease; AHF, advanced hepatic fibrosis; crude model was not adjusted. Adjusted model 1 adjusted for age, sex, race, education level, and ratio of family income to poverty. Adjusted model 2 adjusted for model 1 + smoking status, work activities status, and recreational activities status. Adjusted model 3 adjusted for model 2 + dietary energy intake, dietary protein intake, dietary alcohol intake, dietary sugar intake, dietary fat intake, dietary cholesterol intake, dietary sodium intake, and dietary zinc intake. Adjusted model 4 adjusted for model 3 + hypertension status, and diabetes status. Adjusted model 5 adjusted for model 4 + uric acid, fasting glucose, glycohemoglobin, total cholesterol, HDL cholesterol, creatinine, and BMI.
