Differentially expressed metabolites in fecal samples. (A) Heatmap of the top 50 differentially expressed metabolites in each group (horizontal clustering). (B) Differentially expressed long-chain fatty acids among the four groups. (C) Volcano plot of differentially expressed metabolites in groups C and CT. n = 8 per group. Abscissa: metabolite difference multiple takes two as the bottom logarithm, Ordinate: significance takes 10 as the bottom negative logarithm. Red dots represent significantly up-regulated differential metabolites, blue dots represent down-regulated metabolites, gray dots represent insignificant differences in metabolites
