GPT and metabolic dysfunction-associated steatotic liver disease: The fourth quartile of TyG was associated more closely with NAFLD risk than the fourth quartile of ALT in either normal (adjusted ORs for TyG vs. ALT: 5.6 (4.7–6.8) vs. 2.4 (2.0–2.9)) or elevated ALT group (adjusted ORs: 7.3 (4.3–12.3) vs. 1.2 (0.7–1.8)) (Additional file 1: Table S1).
