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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This observational study measures the carbon footprint produced during upper GI endoscopy in 75 patients with either dyspepsia (diagnostic scope) or non-variceal upper GI bleeding (therapeutic scope). Researchers track emissions from when a patient enters the endoscopy room until they leave. The goal is to compare environmental impact between diagnostic and therapeutic procedures and across different bleeding-control techniques.

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 study could help hospitals understand and reduce the environmental impact of common endoscopic procedures.
What could go wrong
This is a small observational study (75 participants) that only measures carbon footprint during the procedure, not overall healthcare impact. Results may not apply to other settings.

This is an AI summary of the original study and may miss details. Read our disclaimer.
