In the male participants, after adjusting for age, AST, ALT, total cholesterol, hemoglobin, eGFR, and uric acid, those with MetS (p < 0.001), high BMI (p < 0.001), high WHtR (p < 0.001), high WHR (p = 0.024), high LAP (p < 0.001), high BRI (p < 0.001), high CI (p < 0.001), high VAI (p < 0.001), high BAI (p = 0.002), high AVI (p < 0.001), high TyG index (p < 0.001), and high HIS (p < 0.001) were significantly associated with NAFLD. This evidence concerns the gene GPT and metabolic syndrome.
