Table 4. OPLS-DA coefficients obtained from the NMR data of amniotic fluid metabolites from the COS and CON groups.

Metabolites	OPLS-DA coefficient (r)^a
Metabolites	COS versus CON^b
Lysine	+0.773
Citrate	+0.798
Glucose	+0.868
Hypoxanthine	−0.806

^aMetabolite keys are shown in Table 3; correlation coefficients were calculated from the OPLS-DA results with positive and negative signs respectively indicating positive and negative concentration correlations. OPLS-DA: Orthogonal projection to latent structure with discriminant analysis.

^bCON: A corn-soybean basal diet; COS: Chitosan oligosaccharide (the basal diet supplemented with 100 mg/kg chitosan oligosaccharide).
