Model 1: Adjusted age and sex.

Model 2: Model 1 plus living alone, current smoking, exercise, waist-to-height ratio, systolic blood pressure, diastolic blood pressure, alanine aminotransferase, aspartate aminotransferase, total bilirubin, total cholesterol and diabetes.

NAFLD, non-alcoholic fatty liver disease; TyG, triglyceride glucose.
