Fig. 2From: Prognostic significance of MRI-based late-course tumor volume in locoregionally advanced nasopharyngeal carcinomaROC curve to show the AUC of T category, Vpre, LCV, VRR and LCV plus VRR for LRFS. ROC receiver operating characteristic, AUC area under the curve, Vpre tumor volume before treatment, LCV late-course volume, VRR volume regression rate, LRFS local recurrence-free survival, CI confidence interval; P value indicates the difference in the c-indexesBack to article page
