Correlation between the abundances of short-chain fatty acid (SCFA)-generating bacterial species and fecal SCFA concentrations: (A) Butyricicoccus spp.; (B) Faecalibacterium prausnitzii; (C) Roseburia spp. Acetic acid in green; propionic acid in red; butyric acid in blue. Correlations were calculated with Spearman’s rank test, n = 103. Significance of correlation is indicated: *** p < 0.001 and * p < 0.017 (level of significance after Bonferroni correction).
