Significant results from the four group Kruskal–Wallis analysis.
This table represents the taxa that have higher abundance in the control samples when compared with the high Firmicutes:Bacteroidetes ratio IBS clusters.
Values are shown as the median and associated IQR for the percentage of reads for the taxa in each group.
