Identification of a nomogram based on an 8-lncRNA signature as a novel diagnostic biomarker for head and neck squamous cell carcinoma

Figure 7. Validation of the model by the qRT-PCR set (n=102). (A) Distribution of 8-lncRNA-based signature scores, lncRNA expression levels and patient survival durations in the qRT-PCR validation set. (B) Kaplan-Meier curves of OS based on the 8-lncRNA signature. (C) ROC curve analyses based on the 8-lncRNA signature. (D) Calibration curves of the nomogram for the estimation of survival rates at 2 and 3 years. (E) Kaplan-Meier curves of OS according to the total risk score. (F) ROC curves according to the nomogram and lncRNA signature score.
