HPV-Related Prognostic Signature Predicts Survival in Head and Neck Squamous Cell Carcinoma

Figure 3

Validation of the prognostic signature. (a) Kaplan–Meier curve for overall survival, the blue curve represents the low-risk group and red curve represents the high-risk group; (b) Kaplan–Meier curve for progression-free survival, the blue curve represents the low-risk group and red curve represents the high-risk group; (c) principal component analysis without prognostic signature, the blue dots represent patients in the low-risk group and red dots present patients in the high-risk group; (d) principal component analysis with prognostic signature, the blue dots represent patients in the low-risk group and red dots present patients in the high-risk group; (e) heat map of HPV-related signatures expression; (f) survival status plot based on prognostic signature; and (g) risk score plot classified by prognostic signature.
