Fig. 1

PCA score diagram in NEG mode and POS modeIn the figure, the ellipse represents the 95% confidence interval, and the abscissa PC [1] and ordinate PC [2] represent the score of the principal component ranking first and second, respectively. The scatter shapes and colours represent the different experimental groups

OPLS-DA score in the NEG mode and POS modeIn the figure, the ellipse represents the 95% confidence interval, and the abscissa t[1]P represents the predicted principal component score of the first principal component. The ordinate t[1]O represents the orthogonal principal component score, and the scatter shapes and colours represent the different experimental groups

Interaction network diagram of six biomarker differential metabolites. Red indicates that the metabolites are up regulated in group T, blue indicates that the metabolite is down regulated in group T, yellow indicates metabolic pathways, and metabolites without a coloured background are the upstream and downstream substances that are differentially metabolised
