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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 how many coronary artery bypass surgeries a surgical resident needs to perform to become skilled at using two imaging tools: transit-time flowmetry and high-frequency ultrasound. These tools help check the quality of the new blood vessels during surgery. The study enrolled 80 adult patients and tracked the residents' progress. The goal is to improve training and encourage wider use of these tools.

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 help standardize training for surgeons using these imaging tools during bypass surgery.
What could go wrong
This is a small, observational study that only measures learning curves, not patient outcomes. Results may not apply to all hospitals.

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