Fig. 4

ROC curve depicting the ability of serum Neu5Gc levels determined by the optimized SubB2M-A12-SPR assay to distinguish breast cancer patients from cancer-free (normal) individuals. Sensitivity% (true positive rate; ability to detect disease) is plotted against 100%-specificity% (false positive rate or 100%-true negative rate; ability to detect lack of disease). ROC analyses were performed with the data shown in Fig. 3A using Graphpad Prism 8.0
