Feature selection process for mortality based on Boruta’s algorithm (A, C, E, G) and the value evolution of Z-score in the screening process (B, D, F, H). In A, C, E, and G, the horizontal axis represents the variable name and the vertical axis represents the Z-values of each variable. In B, D, F and H, the horizontal axis represents the number of iterations, and the vertical axis represents the change in Z-values during the screening process. The blue boxes and lines correspond to the minimum, average, and maximum Z-scores for a shadow feature. The green boxes and lines represent the confirmed variables and the red ones represent the rejected variables in the model calculation.
