Figure 3

ROC curves of LR methods for classification. (a) ROC curve of the validation set; the AUC in discriminating early recurrence was 0.83 (the sensitivity and specificity were 0.69 and 0.71, respectively). (b) ROC curve of the training set; the AUC in discriminating early recurrence was 0.83 (the sensitivity and specificity were 0.80 and 0.83, respectively). Red curves represent patients with early recurrence, and green curves represent those without early recurrence.
