ROC curves show that SPG20 is a biomarker for colorectal carcinomas and adenomas. The area under the ROC curve (AUC) signifies the accuracy of the SPG20 biomarker for distinguishing colorectal carcinomas (blue line) and adenomas (green line) from normal colorectal tissue samples. AUC, area under the curve; ROC, receiver operating characteristics; SPG20, spastic paraplegia-20.
