Identification of independent prognostic factors by Cox analysis, and construction and evaluation of risk models. A: Forest plot of multivariate Cox regression. B: Risk score curve. C: Increased number of patient deaths were associated with an increasing risk score. D: Heat map of the five identified gene expression profiles. E: KM curve based on risk score. A worse OS was observed in the high-risk group compared to the low-risk group. F: ROC curve showing the prognostic data for the five combined genes at 1, 3, and 5 years. The figure was made by R software (R, version 4.1.2, University of Auckland, New Zealand)
