Serum and urine metabolomic fingerprinting in diagnostics of inflammatory bowel diseases

Table 4 The partial least-squares-discriminant analysis models obtained from proton nuclear magnetic resonance-based analysis of urine samples

Comparison	Model	P value	Q2 (cum)	Number of latent variables
CD vs UC	PLS-DA	0.388	0.1	2
CD active vs UC active	PLS-DA	1.000	-0.2	2
IBD active vs control	PLS-DA	0.003	0.6	4
IBD remission vs control	PLS-DA	0.037	0.31	2
IBD active vs IBD remission	PLS-DA	0.003	0.38	3

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