Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Since this study is measuring ultrasound rectal diameter to help diagnose functional constipation in children, could an ultrasound measurement like this be a useful tool in figuring out whether my child's constipation is functional, and is that something you already use or have access to?
2This trial is no longer actively enrolling — does that mean the results might be available soon, and would those findings change how you approach diagnosing or treating my child's constipation?
3The study is looking at how accurately rectal diameter measured by ultrasound can identify Rome IV functional constipation — how does my child's current diagnosis compare to the Rome IV criteria, and does that affect the next steps you'd recommend?
4Since this appears to be a diagnostic study rather than a treatment trial, what tests or tools are you currently using to confirm my child has functional constipation, and is ultrasound measurement something that might add useful information in our case?
5If ultrasound turns out to be a reliable way to measure rectal diameter for diagnosing constipation, how might that change the approach to monitoring my child's progress compared to what we're doing now?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
