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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether an automated phone system that calls smokers with coronary heart disease after hospital discharge can help them quit. Participants receive calls at several time points over six months, checking on their smoking and offering support. The goal is to see if this approach leads to more people staying smoke-free for up to a year compared to standard care.

What this could mean

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

Active substance
Interactive voice response system
What this could lead to
If effective, this automated phone support could become a low-cost tool to help heart patients quit smoking, reducing their risk of future heart problems.
What could go wrong
This is a single-center trial with 440 participants, so results may not apply broadly. The intervention relies on self-reported abstinence, which may be less reliable than biochemical verification.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
