Differences in Gut Microbiota between Healthy Individuals and Patients with Perianal Abscess before and after Surgery

Figure 7

Linear discriminant analysis effect size (LEfSe) analysis of the differences in the composition of gut microbiota composition between (a) control and abscess groups and (b) abscess and surgery groups. The different circle layers show evolutionary relationships among the six taxonomic levels of phylum, class, order, family, genus, and species from the inside to the outside. The larger nodes of each level represent higher abundance of the species. The yellow and red nodes indicate the insignificant and significant differences of the species from the control group. The gates with significant differences are directly marked in the figure, and the species nodes with other different levels are marked with letters, which specifically represent species.
