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 This study
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study checks whether sleep questionnaires can reliably detect obstructive sleep apnea (OSA) in children with Down syndrome, who are at higher risk for the condition. Researchers will compare questionnaire results with overnight sleep studies (the gold standard) in about 81 children aged 2-17. If the questionnaires prove accurate, they could offer a simpler, less burdensome way to screen for OSA in this population.

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 provide a simple questionnaire to screen for sleep apnea in children with Down syndrome, reducing the need for overnight sleep studies.
What could go wrong
This is an observational validation study, not a treatment trial. The questionnaires may not be accurate enough to replace sleep studies, and results may not apply to all children with Down syndrome.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Children with Down syndrome aged 2-17 years who are seen through the Down syndrome clinic at Oregon Health and Science University who either have a recently completed sleep study (within the past 6 months and no surgical treatment for OSA since then) or who will be having a sleep study. Exclusion Criteria: * Presence of tracheostomy * Presence of subglottic or tracheal stenosis * Severe cardiopulmonary disease requiring supplemental oxygen * Parents or caregivers who are unable to read written English or Spanish
