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 This study
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
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 Results may not be published yet.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 will follow 386 critically ill patients on breathing machines to see if losing 10% or more of thigh muscle within the first week in the hospital is linked to a higher chance of dying within 28 days. Researchers will use ultrasound to measure muscle size. The goal is to better understand how muscle wasting affects survival in intensive care.

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 help doctors identify high-risk ICU patients earlier and guide interventions to prevent muscle loss.
What could go wrong
This is an observational study, not a treatment trial. It only looks for a link, not a cause, and results may not apply to all ICU patients.

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