What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study is testing whether a special blood pressure monitor can accurately detect atrial fibrillation, a common heart rhythm disorder. Researchers will compare the monitor's readings with standard diagnostic methods in 392 adults, some with and some without AF. If it works, this could make screening for AF easier during routine checkups.

What this could mean

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

Active substance
Blood pressure monitor (TH-75) with atrial fibrillation detection function
What this could lead to
If successful, this could provide a simple way to detect atrial fibrillation during routine blood pressure checks, potentially leading to earlier diagnosis.
What could go wrong
This is a diagnostic accuracy study, not a treatment trial. The device may not be accurate enough to replace standard ECG diagnosis, and results may not apply to people with pacemakers or other conditions.
