Serum miRNAs with increased levels in more severe NAFLD patients (-27b, -34a, -22, -122, -192 and -21) showed strong correlations with AST, ALT, ferritin levels and the APRI fibrosis score (APRI = AST to Platelet Ratio Index) (Supplementary Table 2). Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
