Fig. 5.

Box-and-whisker plots showing the distribution of taxa representing the patterns of differences observed between IBS with (IBS+Bloat) and without (IBS−Bloat) bloating and HCs. Taxa depicted are a subset of the taxa from Supplemental Table S2 and represent the different patterns of taxonomic variation that shows statistical significance detected by ANOVA. Significant differences between groups (P < 0.05) were defined by Tukey's post hoc test and are indicated by significant difference between HC and IBS−Bloat (a); significant difference between HC and groups IBS+Bloat and IBS−Bloat (b); and significant difference between IBS +Bloat and groups HC and IBS−Bloat (c).
