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 Results may not be published yet.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 tested whether a low-salt, heart-healthy diet (DASH diet) can prevent heart failure in veterans with high blood pressure and metabolic syndrome. 71 veterans received counseling and some also got tailored messages via smartphone or email. The goal was to see if the diet could reduce artery stiffness and heart damage that leads to heart failure.

What this could mean

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

Active substance
dietary counseling and tailored messaging via smartphone or email
What this could lead to
If successful, this could show that a simple dietary change helps prevent heart failure in people with high blood pressure and metabolic syndrome.
What could go wrong
This is a small, early-stage study with only 71 participants, so results may not apply to everyone. Dietary changes can be hard to maintain long-term.
