Schwimmer conducted studies with different cutoff values (ALT > 52 IU/L for females and >44 IU/L for males), as did Radetti (>40 IU/L), resulting in varying sensitivity (Schwimmer 88% and Radetti 54%) and specificity (Schwimmer 26% and Radetti 100%) for NAFLD [1,41]. This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
