Feature selection curves for each model. (a) Cross-validated AUC scores versus the number of selected features for different models. The optimal number of features and corresponding AUC scores are annotated for each model. (b) SHAP values showing the impact of each feature on model predictions. Features are ranked by their absolute SHAP values, with blue indicating lower values and red indicating higher values. ALB and CRP showed the strongest impact on model predictions
