Ruminococcaceae abundance in INRs. A Relative distributions of families in the two groups are shown. Each bar represents the mean relative abundance of the microbial family. B Ruminococcaceae abundance was lower (P = 0.0076) in the CD4 count < 200 cells/µL group compared to the CD4 count > 200 cells/µL group. *P < 0.05 (Mann–Whitney test)
