Serum and urine metabolomic fingerprinting in diagnostics of inflammatory bowel diseases

Table 2 The partial least-squares-discriminant analysis models obtained from proton nuclear magnetic resonance-based analysis of serum samples

Comparison	Model	P value	Q2 (cum)	Number of latent variables
CD vs UC	PLS-DA	0.069	0.43	2
CD active vs UC active	PLS-DA	0.798	0.46	2
IBD active vs Control	PLS-DA	< 0.001	0.79	4
IBD remission vs Control	PLS-DA	0.372	0.26	2
IBD active vs IBD remission	PLS-DA	0.002	0.76	2

CD: Crohn’s disease; UC: Ulcerative colitis; IBD: Inflammatory bowel diseases; PLS-DA: Partial least-squares-discriminant analysis.
