Figure 4.

Scatter plot SHAP summary showing six features—anticoagulants, BMI, procalcitonin, history of thrombosis, concomitant respiratory failure, WBC—mapped by SHAP value to indicate their impact on model output. Dots range from blue for low to red for high feature values.

A scatter plot of SHAP values. This plot is utilized to elucidate the influence of individual features on the model output within the RF model. The x-axis represents the SHAP values, which quantify both the magnitude and direction of the impact of each feature on the model’s prediction outcomes. The y-axis lists the names of the various features. Each point in the figure corresponds to a single sample, with the color of the point indicating the magnitude of the feature value—red signifies a high feature value, while blue denotes a low feature value. The position of the point along the x-axis reflects the direction and extent of the feature’s influence on the model output. BMI = Body Mass Index, WBC = White Blood Cell.
