Trial Outcomes & Findings for MTT for Children With Both Pitt Hopkins Syndrome and Gastrointestinal Disorders (NCT NCT04132427)
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.
