LDA of the fecal microbiota in study population by abdominal bloating (A) and by IBS subtypes based on bowel characteristics (B). LDA analysis was performed on the CMM and values for the first 2 LDA functions are plotted for the HC and each of the IBS subtypes. The bar charts below the LDA plots show the standardized LDA functions of taxa showing statistically significant differences between subgroups by ANOVA. CIBS, constipation-predominant IBS; DIBS, diarrhea-predominant IBS; MIBS, mixed-bowel-pattern IBS.
