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
The trial has finished. Results may not be published yet.
Stopped early This study
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This status has not been confirmed recently, so it may be out of date.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 tested whether the ultrasound tip of an EBUS bronchoscope, placed on the chest, can detect pneumothorax (collapsed lung) as well as a standard ultrasound probe. Researchers enrolled 17 patients, including those with and without pneumothorax. The goal was to see if this method could replace chest X-rays, reducing radiation exposure. The study was terminated early, so results are limited.

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 allow doctors to quickly rule out pneumothorax after bronchoscopy without a chest X-ray, reducing radiation exposure.
What could go wrong
This was a small feasibility study that was terminated early, so results are limited. The technique may not be accurate enough to replace standard imaging.
