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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at whether tiny molecules in the blood, called microRNAs, can help tell if someone with a mild head injury has actual brain damage visible on a CT scan. Researchers took blood samples from 155 people with mild traumatic brain injury and compared those with and without brain lesions, plus a healthy control group. The goal was to see if these blood markers could replace or reduce the need for CT scans, but the results showed no significant differences between the groups.

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 lead to a simple blood test to quickly identify which mild head injury patients have hidden brain damage.
What could go wrong
This is a small pilot study, not a treatment trial. The biomarkers tested did not show significant differences between groups, so the approach may not be useful in practice.
