Serum and urine metabolomic fingerprinting in diagnostics of inflammatory bowel diseases

Figure 4 Receiver operating characteristic curves based on partial least-squares-discriminant analysis models for nuclear magnetic resonance spectra. A: Serum samples; B: Urine samples. Serum: Red - IBD active vs control (AUC = 0.992); Green - IBD active vs IBD remission (AUC = 0.883). Urine: Red - IBD active vs control (AUC = 0.900); Green - IBD active vs IBD remission (AUC = 0.909); Violet - IBD remission vs Control (AUC = 0.871). IBD: Inflammatory bowel diseases; AUC: Area under curves.
