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.

Stopped early This study
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 aimed to see if a blood test measuring platelet function could predict neurological events like stroke in people undergoing carotid artery surgery. Researchers planned to enroll 650 patients but the study was terminated early. The test uses a device called Multiplate to check how sticky platelets are, which might be linked to stroke risk.

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 patients at higher risk for stroke after carotid surgery, allowing for more personalized care.
What could go wrong
The study was terminated early, so results may be incomplete. It was an observational study, not testing a new treatment, so it cannot directly improve outcomes.
