Data are presented as the mean ± SEM. Comparison: Kruskal–Wallis with Dunn’s post test, ^acontrols vs. total IBS patients before FMT, ^bcontrols vs. total IBS patients after FMT, ^ccontrols vs. PI IBS patients before FMT, ^dcontrols vs. PI IBS patients after FMT, ^econtrols vs. idiopathic IBS patients before FMT, ^fcontrols vs. idiopathic IBS patients after FMT; and Paired t test, ^gtotal IBS patients before vs. after FMT, ^hPI-IBS patients before vs. after FMT, ^IIdiopathic IBS patients before vs. after FMT. FMT, fecal microbiota transplantation; IBS, irritable bowel syndrome; PI, post-infectious.

The bolded numbers are significant values <0.05.
