Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study asks whether a wearable AI ring and a simple clinical exam can accurately diagnose obstructive sleep apnea (OSA) compared to the standard overnight sleep lab test. Adults with suspected OSA will wear the ring during a full lab sleep study, and their results will be compared to the lab's measurements. If the ring and exam prove reliable, they could offer a more convenient and accessible way to detect sleep apnea.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Belun Ring (AI wearable device) and CES-EES clinical scoring
What this could lead to
If accurate, this could make sleep apnea diagnosis simpler, cheaper, and more accessible, reducing the need for overnight lab stays.
What could go wrong
The ring and exam may not match the lab's accuracy, and the study is small and early, so results may not apply to everyone.
