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
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 This study
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 Results may not be published yet.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 looked at whether monitoring oxygen levels at home for 14 nights gives a more accurate diagnosis of obstructive sleep apnea than the standard single-night test in a hospital. Researchers enrolled 130 adults with suspected sleep apnea. They compared results from home monitoring with the in-hospital sleep study to see if multiple nights reduce false positives and false negatives. The goal is to improve how sleep apnea is diagnosed and treated.

What this could mean

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

Active substance
pulse-oximetry (home sleep monitoring device)
What this could lead to
If successful, this could show that home monitoring over multiple nights gives a more accurate diagnosis of sleep apnea than a single-night hospital test.
What could go wrong
This is a small, completed study with 130 participants. It only tests diagnostic accuracy, not treatment outcomes, so the real-world impact on patient care is uncertain.
