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 Results may not be published yet.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.

Summary

This study follows 30,000 people in Korea who experienced cardiac arrest outside a hospital, tracking their survival and brain function for up to six months. The goal is to understand the factors that influence outcomes, which could help improve emergency care and resuscitation practices. Participants are adults with presumed cardiac causes of arrest, excluding those with terminal illness or non-cardiac causes like trauma.

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
This research could help identify patterns in cardiac arrest survival and recovery, potentially guiding better emergency treatments and public health strategies.
What could go wrong
As an observational study, it cannot prove what causes better outcomes, and results may not apply to other countries or healthcare systems.
