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
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 Results may not be published yet.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

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)

Summary

This study follows 1,000 adults having non-cardiac surgery to see if being frail before the operation increases the chance of acute kidney injury afterward. Researchers will also check if changes in blood pressure during surgery help explain this link. The goal is to better understand risks and improve patient 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 this study finds a clear link, it could help doctors identify frail patients early and adjust care to prevent kidney injury after surgery.
What could go wrong
This is an observational study, not a treatment trial. It can show connections but cannot prove cause and effect. Results may not apply to all patients.

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