From: Stool energy density is positively correlated to intestinal transit time and related to microbial enterotypes

Enterotypes differ in proteolytic metabolites in faeces and urine. a Heatmap showing Spearman correlation coefficients of the associations between dry stool energy density, intestinal transit time and faecal short-chain fatty acids (SCFAs). Faecal concentration of SCFAs according to the three enterotypes with respect to b the SCFAs acetate, propionate and butyrate, c the branched SCFAs isobutyrate, 2-methylbutyrate, and isovalerate, as well as d valerate and caproate. e Log-transformed urinary relative levels of the microbial-derived proteolytic metabolites p-cresol sulfate, p-cresol glucuronide, and phenylacetylglutamine according to enterotypes. Differences between enterotypes were detected using the Mann-Whitney U test. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
