Fig. 4: Differences in KEGG metabolic functions encoded by the gut microbiomes of EPG and PPG.

a Sankey diagram connecting the four major metabolic pathways (2nd column) from EPG and PPG (1st column) to the predicted bacterial hosts at the phylum (3rd column) and genus (4th column) levels. b Significant between-group differences in KEGG pathways related to metabolism of the fecal microbiota. The significance was assessed using Wilcoxon rank-sum test. c Bubble plots depicting differences in metabolic functions of the microbial hosts at the species level.
