Enrichment of KEGG pathways in microbial genes in different samples. Enrichment of KEGG pathways in microbial genes in different samples. (A) Comparison between subgroup I and subgroup II. (B) Comparison between subgroup I and subgroup III. (C) Comparison between subgroup II and subgroup III. Only pathways with P values of <0.01 and q values of <0.1 (Mann-Whitney U test) are shown. The pathways were sorted by their fold changes in different subgroups (increasing from top to bottom). Red boxes represent subgroup I samples, blue boxes represent subgroup II samples, and green boxes represent subgroup III samples. Lili Ren et al. mSystems 2018; doi:10.1128/mSystems.00199-18
