GPT and metabolic dysfunction-associated steatotic liver disease: Positive associations existed between ALT quartiles and NAFLD risk, with ORs significantly increasing from 2.57 (95% CI [1.99–3.32]) to 12.60 (95% CI [9.79–16.22]) as the ALT quartiles elevated from Q2 to Q4 (Q1 served as reference) (model 1).
