Fig. 3. Univariate and multivariate cox proportional hazards model (Hazard Ratio, HR) to identify independent prognostic factors.
A Univariate cox regression analysis identify of individual factors related to patient survival; B Multivariate cox regression analysis identify independent prognostic factors and the result indicated that our signature could as independent prognostic factors for overall survival (HR: 1.124; 95% CI: 1.091–1.158). Green means the value of hazard ratio in univariate and red means the value of hazard ratio in multivariate analysis. (T: Tumor, N: Lymph Node, and M: Metastasis).
