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.

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 emergency physicians can accurately predict stroke by interviewing witnesses who saw the symptoms start. Researchers asked 235 witnesses to describe what they observed, then compared the doctors' scores to brain scans. The goal was to see if this method could help reduce delays in getting stroke patients to the hospital.

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 emergency teams use witness reports to quickly identify strokes and reduce delays in getting patients to treatment.
What could go wrong
This is a small, completed observational study, not a treatment trial. The approach may not be accurate enough for real-world use or may not generalize beyond this hospital setting.
