ROC curves in portal venous phase. The yellow curve is the poor prognosis group (PP group), and the blue curve is the good prognosis group (GP group). (A) ROC curve of the KNN model in the validation set. The AUC were 0.718 in the PP group (sensitivity and specificity were 0.77 and 0.75, respectively) and 0.718 in the GP group (sensitivity and specificity were 0.75 and 0.77, respectively. (B) ROC curve of the SVM model in the validation set. The AUC were 0.865 in the PP group (sensitivity and specificity were 0.77 and 0.83) and 0.865 in the GP group (sensitivity and specificity were 0.83 and 0.77, respectively). (C) ROC curve of the XGBoost model in the validation set. The AUC were 0.853 in the PP group (sensitivity and specificity were 0.85 and 0.67, respectively) and 0.853 in the GP group (sensitivity and specificity were 0.67 and 0.85, respectively). (D) ROC curve of the RF model in the validation set. The AUC were 0.808 in the PP group (sensitivity and specificity were 0.62 and 0.83, respectively) and 0.808 in the GP group (sensitivity and specificity were 0.83 and 0.62, respectively). (E) ROC curve of the LR model in the validation set. The AUC were 0.865 in the PP group (sensitivity and specificity were 0.77 and 0.75, respectively) and 0.865 in the GP group (sensitivity and specificity were 0.75 and 0.77, respectively). (F) ROC curve of the DT model in the validation set. The AUC were 0.644 in the PP group (sensitivity and specificity were 0.54 and 0.75, respectively) and 0.644 in GP group (sensitivity and specificity were 0.75 and 0.54, respectively).
