Figure 5.

Horizontal bar chart showing mean SHAP values for six factors: anticoagulants at 0.37, BMI at 0.05, procalcitonin and history of thrombosis both at 0.04, concomitant respiratory failure at 0.03, and WBC at 0.02. Chart illustrates the relative importance of each factor.

The mean absolute SHAP values (mean(|SHAP value|)) for each feature in the RF model are calculated. These values are utilized to quantify the average degree of influence that each feature exerts on the model’s predictive outcomes. Based on the analysis of the mean SHAP values illustrated in the preceding figure, the average importance of the features with respect to the output of the RF model is ranked. BMI = Body Mass Index, WBC = White Blood Cell.
