GPT and metabolic dysfunction-associated steatotic liver disease: Figure 1 graphically demonstrates these results. For NAFLD, ALT was the most important variable (SHAP importance =1.02) followed by TG and BMI. For NASH, AST was the most important factor (SHAP importance=0.5) followed by ALT and TG. For advanced fibrosis, AST was the most important risk factor (SHAP importance=0.91) followed by hyperglycemia (A1c) and HDL.
