Multivariate machine learning results for internal and external abdomen CTs: Kaplan–Meier curves on the internal (left and middle column) and external (right column) abdomen CTs for the SI (A), MFI (B), and VFI (C) using the predicted risk scores of the multivariable abdomen-based BCA models trained and tested on patients with known M status (M0 + M1). Also, the averaged feature importance is shown for each model.
