A novel oxidative stress-related gene signature as an indicator of prognosis and immunotherapy responses in HNSCC
Figure 1. Unsupervised clustering analysis for the head and neck squamous carcinoma samples based on the expression of oxidative stress-related genes. (A) Consensus matrices of the TCGA-HNSC cohort with k = 3; 1, 2 and 3 denote the three subgroups. (B) The CDF plot of unsupervised clustering analysis. (C) Relative change in area under CDF curve for k = 2–5. (D) OS survival curves of the three oxidative stress-related subgroups. (E) Visualization of the results of the PCA analysis for the oxidative stress-related genes. (F) Heat map of the expression of the oxidative stress-related genes in the three subgroups.
