Figure 6.

Horizontal bar chart showing SHAP values for six features affecting a model prediction: anticoagulants have the largest negative impact at minus 0.42, followed by BMI at minus 0.08, procalcitonin at plus 0.03, concomitant respiratory failure at minus 0.03, white blood cell count at plus 0.02, and history of thrombosis at minus 0.02. Positive impacts are shown in pink and negative impacts in blue.

The SHAP waterfall plot for patients at low risk of thrombosis. A waterfall plot illustrates the impact of different variables on a function f(x), as well as the cumulative effect of these impacts. 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.
