Fig. 2From: Compositional variation of the human fecal microbiome in relation to azo-reducing activity: a pilot studyBean/Violin plots representing the relative abundance of core phyla (A and B) and gut microbiome biomarkers (C) among fecal samples of different grades of azo-reducing activity. Phyla in panels A and B are separated because of different scales. p-values of significant differences (p < 0.05), as assessed by Kruskal–Wallis test, are indicated above each plot. p-values of significant differences upon pairwise post hoc tests are indicated as wellBack to article page
