Figure 8. The evaluation of built DFS nomograms. The ROC curves and DCA curves of the comparison between clinical-relevant, pre-treatment and post-treatment survival DFS models in 3, 5, and 7 years. The ROC curves of 3-year survival (A), 5-year survival (B) and 7-year survival (C). The DCA curves of 3-year survival (D), 5-year survival (E) and 7-year survival (F).
