Identifying Clinicopathological Risk Factors of the Regional Lymph Node Metastasis in Patients with T_1-2 Mucinous Breast Cancer: A Population-Based Study

Figure 4

Calibration curves of the nomogram of training cohort for predicting regional lymph node metastasis (LNM) in female patients with T1-2 pure mucinous breast cancer (bootstrap 1000 repetitions). The x-axis represents the predicted regional LNM. The y-axis represents the actual LNM. The diagonal dotted line stands for a perfect prediction using an ideal model. The solid line represented the performance of the nomogram, of which the closer fit to the diagonal dotted line represents the better prediction of the nomogram we constructed.
