Increasing BMI had a greater effect on ALT (MetS-BMI interaction p = 0.033), AST (MetS-BMI interaction p = 0.045), NAFLD score (MetS-BMI interaction p < 0.001) and estimated liver fat % (MetS-BMI interaction p < 0.001) in those with MetS compared with those without MetS (Table 2). Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
