What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting 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 Results may not be published yet.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 tested whether special ultrasound scans can detect kidney damage in people who have received a kidney transplant. 141 transplant recipients had ultrasound imaging at 15 days, 3 months, and 12 months after surgery. The goal was to see if these scans could measure kidney stiffness and blood flow as accurately as a biopsy to diagnose chronic kidney disease.
