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.
1This trial looked at whether a lung development mismatch called dysanapsis might explain why some people have both asthma and obstructive sleep apnoea — could that be a factor in my own case, and would it change how my conditions are managed?
2Since this study has already been completed, has any of its data been published, and could you share what the findings might mean for someone with my combination of asthma and OSA?
3The trial was observational and not testing a treatment — so based on whatever it found about dysanapsis, are there any new diagnostic tests or treatment adjustments I should be considering for my asthma or sleep apnoea?
4Given that this trial focused specifically on patients who have both asthma and OSA, do you think my current treatment plan is addressing how these two conditions might be connected, or are they still being treated as completely separate issues?
5If dysanapsis turns out to be relevant to my situation, does that point toward any different specialists I should be seeing, or any specific investigations like lung function or sleep studies that I haven't had yet?

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.
