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 Results may not be published yet.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

Summary

This study used brain scans (fMRI) to look at how people process emotions and make decisions, comparing those who have attempted suicide, those with past suicidal thoughts, depressed patients without suicidal history, and healthy controls. The goal was to find brain activity patterns linked to suicide vulnerability. The study involved 26 participants and has already been completed.

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 identify brain markers that predict suicide risk, potentially leading to better screening and prevention strategies.
What could go wrong
This is a small, early-stage observational study with only 26 participants, so results may not apply broadly. It does not test any treatment.

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