The mixed Lift curves of the eight machine learning models for prediction of CLNM. The drawing process of the Lift curve is similar to the ROC curve, the difference is that the Lift value and the robust plane pose change in opposite directions, forming the opposite form of the Lift curve and the ROC curve. (A) The mixed Lift curves in the training cohort; (B) The mixed Lift curves in the validation cohort. CLNM, Central lymph node metastasis; ROC, receiver operating characteristic; LR, Logistic Regression; GBM, Gradient Boosting Machine; XGB, Extreme Gradient Boosting; RF, Random Forest; DT, Decision Tree; NNET, Neural Network; SVM, Support Vector Machine; BN, Bayesian Network.
