Differential metabolite extraction and KEGG pathway enrichment analysis. a Volcano plot of the differentially abundant metabolites. The abscissa is the multiple change value of the expression difference of metabolites between the two groups, and the ordinate is the statistical test value of the expression difference of metabolites (p-value). Each point in the figure represents a specific metabolite. b Heatmap of the differentially abundant metabolites between the two groups (variable importance in projection [VIP] scores > 3, p < 0.05). The color represents the relative abundance of the metabolites in the samples. c Level 1 and 2 KEGG pathways related to the differentially expressed metabolites. The ordinate is the name of the level 2 pathway and the abscissa is the number of metabolites related to that pathway. Different colors represent different level 1 pathways. d KEGG pathway enrichment column chart. The abscissa is the name of the level 3 pathway.
