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 This study
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 Results may not be published yet.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.
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.

Summary

This study will enroll 20 children with a narrow upper jaw to see if their jaw shape is linked to sleep apnea. Researchers will use a home sleep monitor to measure breathing pauses during sleep and compare that to dental X-rays and exams. The goal is to understand how jaw development and sleep-disordered breathing are connected in growing kids.

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 study could help dentists and doctors identify children at risk for sleep apnea based on jaw shape, leading to earlier treatment.
What could go wrong
This is a small, early observational study with only 20 children. It is not testing a treatment, so it cannot prove that jaw expansion helps sleep apnea.
