ROC curves depicting the predictive performance of generated classifiers in each comparison. (a) ROC curve illustrating performance of the NMR model in distinguishing liver-only metastases from locoregional CRC. (b) ROC curve illustrating performance of the GC-MS model in distinguishing liver-only metastases from locoregional CRC. (c) ROC curve for the NMR model distinguishing extrahepatic metastases from liver-only metastases. (d) ROC curve for the GC-MS model distinguishing extrahepatic metastases from liver-only metastases. AUC, area under the ROC curve; FPF, false positive fraction; TPF, true positive fraction.
