  1. aThe intratumoral radiomics model was built using 13 algorithms: Random Forest (RF), Decision Tree (DT), Extra Trees (ET), Support Vector Machine (SVM), Logistic Regression (LR), Stochastic Gradient Descent (SGD), K-Nearest Neighbors (KNN), XGBoost, AdaBoost, Gradient Boosting Decision Tree (GBDT), CatBoost, LightGBM, and Bayes. AUC: area under curve, ACC: accuracy, SEN: sensitivity ,SPE: specificity, PPV: positive predictive Value, NPV: negative predictive value, CI: confidence interval.
