The SHAP summary plot of the RF model. (A) The SHAP bar plot for the ranking of the importance of variables. The sorted result was based on the mean absolute SHAP value of each variable in the RF model. (B) The SHAP bee swarm plot for the entire distribution of the SHAP values for each variable of the RF model. Each line represents a variable and each dot represents a case. The greater the intensity of the red color of the dot, the higher the value of the variable for the case. In contrast, the greater the intensity of the blue color of the dot, the lower the value of the variable for the case. The abscissa represents the SHAP value; a positive SHAP value helps the model predict the case of developing hypoxemia, and vice versa.
