KEGG differential metabolic pathway analysis. A, B, Histograms of KEGG enrichment pathways, in which the vertical axis represented each KEGG metabolic pathway, and the horizontal axis represented the number of differentially expressed metabolites contained in each KEGG metabolic pathway. C, D, The Differential Abundance Score, which was proportional to the color of the dot and the DA score value. E, F, A clustered heat map of differential metabolites of the KEGG pathway, and the color block at different locations represented the relative expression of metabolites
