Figure 6 Development of the nomogram.
Notes: The nomogram can provide individual patients with a probability of 1–5 years disease-free survival (A) and cancer-special survival (B) based on the sum of the scores for each variable predicted at the bottom scale.
Abbreviations: DFS, disease-free survival; CSS, cancer-special survival.
