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

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 Results may not be published yet.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.

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 looks at whether giving critically ill patients on breathing machines less protein (0.6-0.8 g/kg per day) during their early ICU stay leads to a better quality of life after leaving the hospital, compared to the standard amount (1.3 g/kg per day). About 1,026 adults will take part across multiple hospitals. The goal is to see if lower protein intake helps patients feel better and recover more fully over the following months.

Participants

About 1,026 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start
