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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 completed study tested a remote, self-guided lifestyle program for 696 veterans with obesity and obstructive sleep apnea. Participants watched videos, completed handouts, and tracked their eating and activity, with optional coaching. The goal was to see if this low-cost approach could improve sleep-related quality of life and help with weight loss compared to usual care alone.

What this could mean

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

Active substance
lifestyle intervention (diet and exercise program with coaching)
What this could lead to
If successful, this approach could offer a practical, scalable way to help people with sleep apnea lose weight and improve their sleep-related quality of life without needing intensive in-person programs.
What could go wrong
The intervention is self-directed and remote, so results may vary widely. Weight loss and health improvements may be modest, and the study only included veterans, so findings may not apply to everyone.
