Fig. 3From: Application of preoperative ultrasound features combined with clinical factors in predicting HER2-positive subtype (non-luminal) breast cancerThe receiver operating characteristic curve of the predictive model for the HER2 positive subtype in the test set. This figure shows that the model with combined clinical and ultrasound features had moderate predictive power for HER2+ subtype, with an AUC of 0.725 in the test set.
