Species showing significant differences in abundance across the four groups as defined from the Kruskal–Wallis analysis.
Values are shown as the median and associated IQR for the percentage of reads for the taxa in each group.
↵* Sporobacter termitidis and Eubacterium siraeum have both the highest and lowest values in the IBS clusters but are presented in this table as having their highest values in IBS cluster 2.
