Literature-Informed Risk Prediction Models Figure shows SHAP summary plots displaying the effect of a feature and its value on the prediction. The y-axis of each plot contains the features included in the model sorted from the most (top) to least (bottom) important. The x-axis depicts the SHAP value. Each point refers to a SHAP value associated with a value of a certain feature. The color of the point displays whether the feature value is high (pink) or low (blue). Grey-colored points are categorical and missing values. Example: Age in subplot A: Older ages (red-colored points) increase the risk of SSI (SHAP value 0.5 to 1), lower ages (blue-colored points) reduce the risk (SHAP values − 0.9 to − 0.5). (A) Preoperative SSI model (B) Postoperative SSI model (C) Preoperative Leak model (D) Postoperative Leak model.
