What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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.
Cancelled
Cancelled before anyone took part.

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 will check how common it is for obese people with sleep apnea to still have low breathing at night even when using a CPAP machine. About 139 adults will wear a special skin sensor that measures oxygen and carbon dioxide levels overnight. The goal is to find out how many people need additional treatment for this hidden breathing problem.

What this could mean

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

What this could lead to
If successful, this could help doctors identify which obese sleep apnea patients need extra breathing support beyond CPAP.
What could go wrong
This is an observational study, not a treatment trial. It only measures a problem without testing any new therapy, so it won't directly improve health.

This is an AI summary of the original study and may miss details. Read our disclaimer.

The number the study aims to enrol. It can still change while the study runs.

Expected to start
