OPLS–DA coefficients derived from the NMR data of plasma metabolites obtained from the (A) control, (B) pea fiber, and (C) wheat bran fiber groups.

aCorrelation coefficients: positive and negative signs indicate positive and negative correlation in the concentrations, respectively. The correlation coefficient of |r| > 0.632 (for B vs A and B vs C) or 0.602 (for C vs A) was used as the cutoff value. “–” means the correlation coefficient |r| is less than 0.632 (for B vs A and B vs C) or 0.602 (for C vs A).OPLS–DA coefficients derived from the NMR data of plasma metabolites obtained from the (A) control, (B) pea fiber, and (C) wheat bran fiber groups.
