NCT ID: NCT04132427

Last Updated: 2024-08-26

Results Overview

The DSR is a daily record of their bowel movements including Bristol Stool Form scale. It is rated as the number of days (out of 14 days) with an abnormal report (abnormal stool, no stool, or the use of a gastrointestinal treatment). A higher percentage indicates worse symptoms.
