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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether telling Taiwanese university students their ALDH2 gene type, which affects alcohol intolerance, changes their drinking habits and attitudes. Participants receive their genotype results along with standard health education about alcohol risks. Researchers measure drinking frequency, amount, knowledge, and attitudes before and one month later. The study also checks if facial flushing and rapid heartbeat can signal ALDH2 deficiency.

What this could mean

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

Active substance
Individual ALDH2 genotype feedback and standardized alcohol health education
What this could lead to
If it works, personalized genetic feedback could help reduce risky drinking in people with alcohol intolerance.
What could go wrong
The trial is small and short-term, and results may not apply beyond university students in Taiwan.
