The ROC curve of PBK/TOPK overexpression for prediction of overall survival. The ROC curve combines the sensitivity and specificity of PBK/TOPK overexpression for breast cancer diagnosis. The closer the curve is to the upper left corner, the larger is the area under the curve, indicating greater diagnostic value. As the ROC curve shows, the experimental ROC curve is close to the upper left corner, and the area under the curve is 0.690 > 0.5, indicating that the model has a predictive value
