Figure 4 Area under the receiver operating characteristic curve curves for training set, internal validation set, and external validation set. A: Area under the receiver operating characteristic curve (AUC) for the training set; B: AUC for the internal validation set; C: AUC for the external validation set. AUC: Area under the receiver operating characteristic curve; Combined: The model that incorporates features from all regions—tumor, 5 mm, and 10 mm.
