The results indicated that FIB-4, APRI, and the AST/ALT ratio exhibited limited predictive capability for NAFLD with liver fibrosis in comparison to NAR, as evidenced by their respective AUC values of 0.535 (95% CI: 0.527–0.543), 0.517 (95% CI: 0.505–0.528), and 0.532 (95% CI: 0.508–0.555) (Supplementary Table S2). This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
