What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 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 Results may not be published yet.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.

Summary

This study investigates whether sleep patterns influence the community of microorganisms living in the human body, known as the microbiota. Researchers will examine how changes in sleep and body weight affect these microbes in healthy people. The goal is to understand if sleep-related shifts in the microbiota could be linked to future disease risk.

What this could mean

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

Active substance
Sleep restriction (behavioral intervention) and weight gain (dietary supplement)
What this could lead to
If sleep patterns are shown to alter the microbiome, this could lead to new ways to predict or prevent diseases linked to poor sleep and gut health.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The results may be influenced by many factors, and the findings might not apply to everyone.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Start date

Expected to finish

Dec 2031

An estimate. End dates often move.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
