Figure 7. Cox regression analysis of clinical correlation indicators and integrated ROC curves. (A) Clinical-related indicators Cox univariate regression analysis showing that tumor grade, clinical stage, TMN stage, and risk score were related to outcome. (B) Cox multivariate analysis showing that risk scores are independent predictors of outcome. (C) The comparison of risk coefficient score and clinical-related indicators showing that risk coefficient score (AUC = 0.867) and tumor stage (AUC = 0.868) had the highest predictive efficacy.
