Outcome Measures
Primary Outcomes (1)
Change From Baseline of Sum of NRS-11 Abdominal Pain and Bloating/Flatulence Intensity Scores After 4 Weeks of Treatment.
The baseline abdominal pain and bloating/flatulence intensity was determined as the average of the Numeric rating scale (NRS-11) daily assessment during 7 days before randomization. The Week 4 assessment was the average from last 7 days of the corresponding week. The scale is a horizontal 10 cm line with the numbers from 0 to 10 located on it, where 0 is "no pain/bloating", 10 is "most severe pain/bloating you can imagine".
4 weeks
