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 This study
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 Results may not be published yet.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
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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are comparing two ways of finding atrial fibrillation in people who have had an ischemic stroke or a transient ischemic attack (TIA). One method uses a standard electrocardiogram (ECG) in the hospital, and the other uses a prolonged cardiac monitor worn for a longer period. The study reviews records from 366 patients in the London Ontario Stroke Registry to see whether the two detection methods are linked to different rates of recurrent stroke, death, or hospital readmission for heart problems.

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 the two detection methods identify different risks, doctors could tailor how closely they watch stroke survivors for recurring atrial fibrillation and future strokes.
What could go wrong
This is a single-center review of past records, so it can show patterns but cannot prove that one monitoring method causes better outcomes. The findings may not apply to other hospitals or patient groups.
