a PCA plot of the TCGA samples generated by using the top hundred proteins selected based on their NetRank scores. The red dots are breast cancer samples, while the blue refers to the other 18 cancer types in the dataset. The two different clusters can be visually separated very easily. b The ROC curve of the first principle component. The high diagnostic ability of these proteins is confirmed by the AUC value of 0.93
