Model interpretation for CD (a), UC (b), and all patients (c). Left: Feature importance (mean |SHAP|). Middle: Feature effects (feature value vs. SHAP contribution). Right: SHAP vs. standardized age; 0 = EBV−, 1 = EBV+. r0 and r1 are Pearson correlations between age and predicted EBV risk within categories 0 and 1.
