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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are studying how the immature heart and breathing systems of premature babies affect their long-term development. The trial enrolls infants born between 24 and 29 weeks of gestation who are less than a week old. Using integrated physiological measures, the team tracks cardiorespiratory coupling from 28 weeks postmenstrual age to 1 year and assesses neurodevelopmental outcomes. The goal is to understand these systems better and find improved ways to help premature infants breathe and develop.

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 researchers learn how heart and breathing rhythms interact in premature babies, this could point toward better ways to support their breathing and development.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Results may not apply to babies born at different gestational ages or with other health conditions.
