Feature importance in the model. The SHAP value reflects the impact of features in each sample and their positive or negative effects. Contributing factors are ranked in descending order of importance in these plots. Each dot presents a sample; red dots present a higher feature value, and the right side of the vertical line (i.e., feature-specific SHAP values of > 0) presents a higher chance of poor prognosis.
