Computed tomography-based radiomic model for the prediction of neoadjuvant immunochemotherapy response in patients with advanced gastric cancer

Figure 4 Receiver operating characteristic curve analysis of the radiomic model and the clinical model. A: The area under the curve (AUC) of the radiomic model was 1.000 [95% confidence interval (CI): 1.000-1.000] in the training cohort; B: The AUC of the radiomic model was 0.750 (95%CI: 0.435-1.000) in the test cohort; C: The AUC of the clinical model was 0.937 (95%CI: 0.868-1.000) in the training cohort; D: The AUC of the clinical model was 0.696 (95%CI: 0.440-0.953) in the test cohort. XGBoost: EXtreme gradient boosting; TPR: True positive rate; FPR: False positive rate.
