Prognostic Correlation of an Autophagy-Related Gene Signature in Patients with Head and Neck Squamous Cell Carcinoma

Figure 5

(a) The Kaplan–Meier plot of the overall survival (OS) for high-risk and low-risk patient cohorts divided by the 6-ARGs signature in the training set (). The OS differences are determined by the two-sided log-rank test. (b) Receiver operating characteristic analysis for the 6-ARG signature in predicting the patients of 1, 3, and 5 years OS in the training set. (c) The distribution of the risk score. Each dot represents a specific patient. The color red indicates high-risk level, and green indicates low-risk level. (d) The distribution of patients’ survival status. Each dot represents a specific patient. The color red indicates dead, and green indicates alive. (e) The heat map displays the relationship between risk score and respective gene expression level of this signature in the training set.
