Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Vibegron 75 mg | Participants received vibegron 75 milligrams (mg), orally, once daily for 12 weeks. Participants were stratified by Baseline API score (\< 6 versus ≥ 6 on a 0- to 10-point numeric rating scale) and IBS subtype (IBS-D versus IBS-M). | 18 | 66 | OG001 |
| Group 2 | Placebo | Participants received matching placebo, orally, once daily for 12 weeks. Participants were stratified by Baseline abdominal pain intensity (API) score (\< 6 versus ≥ 6 on a 0- to 10-point numeric rating scale) and irritable bowel syndrome (IBS) subtype (IBS with predominant diarrhea \[IBS-D\] versus IBS with mixed episodes of diarrhea and constipation \[IBS-M\]). | 13 | 63 | OG000 |
