4-marker model performance in CRC diagnosis. A representative receiver operating curve (ROC) displays the classification performance of the 4-marker model. a In the training set, the area under the curve (AUC) was 0.912. b In the test set, the AUC was 0.907. c In the validation set with advanced adenomas, the AUC was 0.796. d In the validation set without advanced adenomas, the AUC was 0.911. e The performance of the 4-marker model in detecting different stage CRC. HGIN, AUC 0.614. Stage I CRC, AUC 0.868. Stage II CRC, AUC 0.800. Stage III CRC, AUC 0.935. Stage IV CRC, AUC 0.947. f The risk score of the 4-marker model in detecting different stage CRC
