Identifying Clinicopathological Risk Factors of the Regional Lymph Node Metastasis in Patients with T1-2 Mucinous Breast Cancer: A Population-Based Study
Figure 3
Decision curve analysis for regional lymph node metastasis (LNM) in female patients with T1-2 pure mucinous breast cancer (EI-score) in the training cohort and internal cohort. The decision curve analysis graphically shows the clinical usefulness of the EI-score based on a continuum of potential thresholds for regional LNM and the net benefit of using the EI-score to stratify patients (y-axis). Net benefit = (true positives/N)−(false positives/N)(weighting factor). Weighting factor = Threshold probability/(1-threshold probability).
