Identification of fecal metabolites. (a and b) Volcano plot of differential metabolites. Red represents upregulated metabolites, and blue represents downregulated metabolites. (c and d) Heatmap of differential metabolites. The horizontal direction is the name of fecal samples, while the longitudinal direction represents the clustering of metabolites; the shorter the clustering branches are, the more similar the color is, and the higher the similarity is.
