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 Results may not be published yet.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 looked at whether lung ultrasound (LUS) can accurately diagnose pneumonia in children in low-resource settings, where chest X-rays are often unavailable. Researchers compared LUS results to a 'gold standard' diagnosis based on clinical exams, imaging, and lab tests. The goal is to see if LUS can be a practical, reliable alternative to help avoid missed diagnoses.

What this could mean

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

Active substance
lung ultrasound (diagnostic test)
What this could lead to
If successful, lung ultrasound could become a reliable, low-cost tool for diagnosing childhood pneumonia in areas without easy access to chest X-rays.
What could go wrong
This is a completed diagnostic study, not a treatment trial. Lung ultrasound may miss some pneumonia cases, and results may not apply to all settings.
