ROC curves of the scoring system for differentiating between non-advanced and advanced ALNM in the training cohort (A) and the validation cohort (B), and calibration plots of the system for the training cohort (C) and the validation cohort (D). The Hosmer–Lemeshow test indicated goodness-of-fit for the model in the training (χ2 = 3.09, P = 0.69) and validation cohorts (χ2 = 9.44, P = 0.31). The calibration plot of the observed frequency compared to the predicted probability of the scoring model showed slopes of 1.000 for the training cohort (C) and 0.852 for the validation cohort (D). ROC, receiver operating characteristic; ALNM, axillary lymph node metastasis; AUC, area under the curve; CI, confidence interval
