How this model should be used:
This nomogram was developed to predict positive resection margins.
Model performance:
The nomogram was validated independently using a cohort of 563 patients who underwent breast surgery in 2010. The AUC of the validation cohort was 0.846 (95 % CI, 0.800–0.892). Calibration of the nomogram was assessed using an independent validation cohort. In general, the actual proportion of patients with positive resection margins and the predictive probability of positive resection margins were similar, according to the calibration plot.
