Figure 3. Kaplan–Meier and ROC curves for the six microRNA signature in TCGA HNSCC tumor grade group.

A. The ROC curve for predicting 5-year survival had an AUC of 0.660 (95%CI, 0.518-0.778) in the G1-2 group. The 95%CI of AUC were calculated from 1000 bootstrap of the survival data. B. The Kaplan–Meier curves for HNSCC risk groups obtained from the TCGA cohort G1-2 group divided by the cutoff point. The P value of the log-rank test was <0.01. C. The ROC curve for predicting 5-year survival had an AUC of 0.732 (95%CI, 0.613-0.840) in the G3-4 group. The 95%CI of AUC were calculated from 1000 bootstrap of the survival data. D. The Kaplan–Meier curves for HNSCC risk groups obtained from the TCGA cohort G3-4 group divided by the cutoff point. The P value of the log-rank test was <0.01.
