Fig. 2From: 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 training set. This figure demonstrates the predictive ability of the model combing clinical and ultrasound features for HER2+ subtype with an AUC of 0.697 in the training set.
