Interpretable multimodal artificial intelligence model for predicting advanced neoplasia in pancreatic cystic lesions

Figure 3 Relative SHapley Additive exPlanations feature importance for the integrated multimodal model. The bar plot illustrates the relative mean absolute SHapley Additive exPlanations (SHAP) values of predictors in the integrated multimodal model. Enhancing mural nodules demonstrated the greatest contribution to predicted risk of advanced neoplasia, followed by main pancreatic duct diameter, serum carbohydrate antigen 19-9, cyst fluid glucose, cyst fluid carcinoembryonic antigen, and age. Feature contributions are presented as relative mean absolute SHAP values, reflecting overall predictor importance in the model. MPD: Main pancreatic duct; CEA: Carcinoembryonic antigen; CA 19-9: Carbohydrate antigen 19-9; SHAP: SHapley Additive exPlanations.
