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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 completed trial tested whether a 3D imaging device helps doctors more accurately classify colon polyps and adenomas during colonoscopy compared to standard 2D imaging. 460 adults with colorectal polyps were randomly assigned to either 3D or 2D imaging before polyp removal. The goal was to see if 3D improves diagnostic accuracy, using pathology as the gold standard. Participants were followed for 30 days to track any side effects.

What this could mean

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

Active substance
3-dimensional imaging device
What this could lead to
If successful, 3D imaging could help doctors more accurately identify polyps during colonoscopy, potentially reducing the need for repeat procedures.
What could go wrong
This is a single-center study with 460 participants, so results may not apply broadly. The technology may not significantly improve accuracy over standard 2D imaging.
