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.

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.

Summary

This completed study looked at 322 premature babies born before 32 weeks to compare different ways of diagnosing bronchopulmonary dysplasia (BPD), a common lung disease. Researchers proposed a new classification that separates high-flow nasal cannula from other breathing support. They then compared this new standard with older ones to see which best predicts long-term breathing issues and other complications. The goal is to improve diagnosis and help doctors better manage BPD in preemies.

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 lead to more accurate diagnosis and grading of bronchopulmonary dysplasia in premature babies, helping doctors predict long-term breathing problems and other complications.
What could go wrong
This is an observational study comparing diagnostic criteria, not testing a treatment. Even if the new criteria are better, they won't directly improve outcomes without new therapies.
