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 Results may not be published yet.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 is working on a new way to diagnose concussions in athletes using a simple saliva test. Researchers will measure specific molecules in the saliva of 80 male athletes (professional, amateur, and occasional) before, during, and after exercise. The goal is to find reliable biomarkers that can quickly and accurately identify a concussion, which is often hard to detect with standard brain scans.

What this could mean

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

Active substance
Saliva biomarker analysis (nucleic acids and proteins)
What this could lead to
If successful, this could lead to a simple, non-invasive saliva test to quickly diagnose concussions in athletes, reducing reliance on subjective assessments.
What could go wrong
This is an early-stage observational study with only 80 participants, so results may not be generalizable. The biomarkers may not prove reliable enough for a diagnostic test.
