<p>(A: R<sup>2</sup>X = 20.5%, Q<sup>2</sup> = 0.371; B: R<sup>2</sup>X = 28.6%, Q<sup>2</sup> = 0.626; C: R<sup>2</sup>X  = 28.3%, Q<sup>2</sup>  = 0.289). Two plasma samples from pea fiber group, one sample from wheat bran fiber, and one sample from control were excluded because they positioned outside the Hotelling's T<sup>2</sup> elipse on the score plot. The color map shows the significance of metabolite variations between the two classes. The peaks in the positive direction indicate the metabolites that are more abundant in the groups in the positive direction of the first principal component. The metabolites that are more abundant in the groups in the negative direction of the first primary component are presented as peaks in the negative direction.</p
