Figure 3.

Receiver-operating characteristic curves for the outcome prediction of T classification alone and the combination of magnetic resonance imaging (MRI)-detected CN invasion and T classification in NPC (n=749), with death (A), distant metastasis (B), and locoregional recurrence (C) as the end point. The P-values were compared with the T classification alone. *Magnetic resonance imaging–detected CN invasion combined with T classification. Abbreviations: AUC=area under the curve; CN=Cranial nerve; MRI=Magnetic resource imaging.
