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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether an AI tool called GestaltMatcher can help diagnose rare genetic diseases by analyzing facial photos. The study includes about 100 people in Taiwan with suspected genetic conditions and unusual facial features. Doctors will also use eye-tracking to see how they examine faces, and the team will compare facial patterns and diagnostic accuracy between Taiwanese patients and patients from other countries.

What this could mean

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

Active substance
facial photo analysis with an AI system called GestaltMatcher
What this could lead to
If it works, this could help doctors diagnose rare genetic diseases faster and more accurately, especially in people whose facial features differ from the mostly European faces used to train current tools.
What could go wrong
The study is small and focuses on one ethnic group, so the results may not apply broadly. AI facial analysis can miss diagnoses or flag false ones, and it still needs a doctor's judgment.

This is an AI summary of the original study and may miss details. Read our disclaimer.
