From: Proteobacteria explain significant functional variability in the human gut microbiome
Phylum-specific tests reveal hidden variability in the most prevalent bacterial phyla. a, b Venn diagrams showing the number of significantly variable (a) and invariable (b) gene families across Proteobacteria, Bacteroidetes, and Firmicutes, FDR ≤5%. c Bars indicate the fraction of phylum-specific variable gene families that were also variable overall (yellow, “both tests”) or that were specific to a particular phylum (red, “phylum-specific test only”)
