Figure 5. Receiver operating characteristic curve (ROC) analysis and nomogram construction predicted overall survival using risk score. (A, B) ROC analysis for predicting 2-, 3- and 5-year survival times in the training and validation sets. (C) ROC analysis between risk score and clinicopathological characteristics in the training set. (D, E) Calibration curves of the nomogram for predicting the probability of 3- and 5-year survival. (F) A nomogram to quantitatively predict 1-, 2-, and 3-year survival for HNSCC patients based on the prognostic signature and clinicopathological characteristics of the training set.
