Figure 7. Prognostic implications of risk signature. (A) Copy number variation frequency analysis with red dots representing copy number gains and green dots representing copy number deletions. (B) Copy number circle diagram. The outer circle was the chromosome, and the inner circle was marked with three IRGs. The red dots indicated that the copy number of this gene was increased, and the blue point indicated that the copy number of this gene was more deleted. (C, D) Univariate and multivariate Cox regression analyses in the combined cohort. (E–G) The proportion of patients with different gender, stage, and primary therapy outcome in high- and low-risk groups. (H) Survival analysis of patients in high- and low-risk groups based on GSE62254 gene.
