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
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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study looked at 50 intensive care patients to see how a contrast dye used in CT scans changes two kidney injury markers (TIMP-2 and IGFBP7) in urine. The goal was to understand if the dye causes a measurable increase in these markers. It was a small, observational study without a comparison group, so it helps gather knowledge rather than proving a treatment works.

What this could mean

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

Active substance
contrast dye (iodinated contrast agent)
What this could lead to
If successful, this could help doctors better understand how contrast dye affects kidneys in critically ill patients, potentially leading to safer scanning practices.
What could go wrong
This is a small, early observational study with no control group, so results may not apply broadly. It only measures markers, not actual kidney outcomes.
