(A) Univariate Cox regression analysis and (B) multivariate Cox regression analysis demonstrated that the CDI model was an independent prognostic factor. (C) Univariate Cox regression analysis and (D) multivariate Cox regression analysis in high-risk group. (E) A nomogram was constructed using the CDI score and clinicopathological factors to predict 1-year, 3-year, and 5-year relapse-free survival rates in high-risk group. (F) Calibration plots for 1-year, 3-year, and 5-year relapse probabilities in high risk group.
