Trial Outcomes & Findings for A Placebo-Controlled Trial of Pregabalin (Lyrica) for Irritable Bowel Syndrome (NCT NCT00977197)

NCT ID: NCT00977197

Last Updated: 2016-10-28

Results Overview

The Bowel Symptom Scale (BSS) consists of 5 questions, each with a 100 mm long Visual Analog Scale (VAS). The questions are regarding pain, bloating, constipation, diarrhea, and overall severity of Irritable Bowel Syndrome (IBS) symptoms. The VAS does not have any pre-set marks between the extremes of 0 for not present and 100 mm for very severe symptoms. The investigator measures the mark made by the participant in mm and records this for the value.
