Figure 4. Estimation of the prognostic accuracy of the autophagy-related lncRNA prognostic signature and other clinicopathological variables in the BCLA patients. (A) Univariate Cox regression analysis shows the correlation between overall survival and various clinicopathological parameters such as age, gender, AJCC stage, T stage, N stage and the autophagy-related lncRNA prognostic signature risk score. The remaining parameters (P < 0.001) are significantly associated with OS in addition to the gender. (B) Multivariate Cox regression analysis shows that age and risk score (P < 0.001) are independent prognostic indicators for overall survival rates of BCLA patients. (C) Receiver operating characteristic (ROC) curve analysis shows the prognostic accuracy of clinicopathological parameters such as age, AJCC stage, T stage, N stage and autophagy-related lncRNA prognostic risk score.
