Figure 4. KEGG categories enriched or depleted in the core versus variable components of the gut microbiome.

Figure 4

Sequences from each of the 18 fecal microbiomes were binned into the ‘core’ or ‘variable’ microbiome based on the co-occurrence of KEGG orthologous groups (core groups were found in all 18 microbiomes while variable groups were present in fewer (<18) microbiomes; see Supplementary Figure 19A). Asterisks indicate significant differences (Student’s t-test, *p<0.05, **p<0.001, ***p<10−5; mean±SEM).
