FIGURE 6.
Examination of the independence of the risk score predicted by the prognostic model. (A) Univariate COX regression analysis was conducted on clinical traits (age, gender, T stage, N stage, and clinical stage) and the risk score. The forest plot shows HR and p-value of each prognostic factor. (B) Multivariate COX regression analysis was performed on clinical traits and the risk score. (C) ROC curves and AUCs of 3-year survival of each prognostic factor.
