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 Results may not be published yet.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 20 adults with short bowel syndrome who rely on home parenteral nutrition. Researchers compared giving the nutrition overnight versus during the day to see if timing affects blood sugar levels and sleep quality. Participants wore glucose monitors and activity trackers during each one-week feeding schedule.

What this could mean

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

Active substance
timing of parenteral nutrition (daytime vs nighttime feeding)
What this could lead to
If successful, this could point toward better feeding schedules to improve glucose control and sleep quality for people on home parenteral nutrition.
What could go wrong
This is a small, early study with only 20 participants, so results may not apply to everyone. It looks at short-term changes, not long-term health outcomes.
