Bar chart showing the impact of various factors on a prediction model. Anticoagulants have the largest positive effect (+0.3), followed by BMI (+0.04), procalcitonin (+0.03), respiratory failure (+0.01), and WBC (+0.01). History of thrombosis shows a small negative effect (−0.01). Pink bars represent positive contributions, and the blue bar represents a negative contribution.

The SHAP waterfall plot for patients at high risk of recurrence. A waterfall plot is employed to depict the influence of various variables on a function f(x), as well as the cumulative effect of these influences. Each bar in the plot represents the contribution of a variable to the increase or decrease in the function value. BMI = Body Mass Index WBC = White Blood Cell.
