Putting AL ratio, BMI, triglyceride, AST/ALT ratio to the diagnosis performance of NAFLD, the ROC was 0.85 (95% CI: 0.82–0.88), 0.83 (95% CI 0.78–0.87) and 0.86 (95% CI 081–0.91) for all NAFLD, NAFLD in women and NAFLD in men, respectively. Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
