Metabolomics Analysis in Serum from Patients with Colorectal Polyp and Colorectal Cancer by ¹H-NMR Spectrometry

Figure 5

Diagnostic potential for colorectal polyp and CRC by rates (acetate/glycerol, lactate/citrate) from serum data. (a) ROC curves of the rate of acetate/glycerol (colorectal polyp vs. control with a 0.831 AUC, colorectal polyp vs. CRC with a 0.713 AUC, and CRC vs. control with a 0.669 AUC); (b) rate of acetate/glycerol in serum samples from control, colorectal polyp, and CRC patients; (c) ROC curves of the rate of lactate/citrate (colorectal polyp vs. control with a 0.821 AUC, colorectal polyp vs. CRC with a 0.772 AUC, and CRC vs. control with a 0.827 AUC); (d) rate of lactate/citrate in serum samples from control, colorectal polyp, and CRC patients. ; .
