  1. Model 1 was unadjusted
  2. Model 2 was adjusted for age, sex and body mass index
  3. Model 3 was adjusted for all variables in model 2 plus systolic blood pressure, uric acid and white blood cell counts
  4. Model 4 was adjusted for all variables in model 3 plus TyG for ALT quartiles or plus ALT for TyG quartiles
  5. NAFLD: nonalcoholic fatty liver disease; ALT: alanine aminotransferase; Q1: first quartile; Q2: second quartile; Q3: third quartile; Q4: fourth quartile
