Patients with NAFLD had significantly higher levels of TyG and ALT than non-NAFLD subjects in both normal (TyG, 8.8 vs. 8.2; ALT, 22.0 vs. 16.0 U/L; both P < 0.0001) and elevated (TyG, 9.0 vs. 8.3; ALT, 53.0 vs. 49.0 U/L; both P < 0.0001) ALT groups. Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
