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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at 395 adults with obstructive sleep apnea to see if a new tool called the Baveno classification agrees with the standard sleep test (polysomnography) for deciding treatment. Researchers compared symptoms and health records against sleep lab results. The goal is to find out if the Baveno system can help doctors make treatment decisions more easily.

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 the Baveno classification proves useful, it could become a simpler, complementary tool for doctors to decide on sleep apnea treatments without relying solely on overnight sleep tests.
What could go wrong
This is a retrospective study, meaning it looks back at existing data, so it cannot prove cause and effect. The findings may not apply to all patients or change current practice.

Who can take part

Who is studied

The study population consisted of adult patients with obstructive sleep apnea who underwent overnight polysomnography at a tertiary care sleep laboratory between January 2016 and June 2024. Participants were identified through electronic medical records and sleep laboratory archives. Only patients with complete clinical and polysomnographic data, including symptom burden and comorbidity profiles, were included. All patients were evaluated using both polysomnography-based severity classification and the Baveno classification system for comparative analysis.
