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 Results may not be published yet.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.

Summary

This trial tests whether running HEPA air purifiers in classrooms and bedrooms for four months improves heart and lung function in healthy primary school students aged 8 to 12. Researchers will measure heart rate variability, lung capacity, and markers of inflammation in children using the purifiers versus those without. The goal is to see if reducing indoor air pollution can support children's cardiopulmonary health.

What this could mean

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

Active substance
HEPA air purifiers and fresh air ventilation systems
What this could lead to
If effective, cleaner indoor air could become a simple way to protect children's heart and lung health in polluted areas.
What could go wrong
The trial is small and short, and results may not apply to other settings. Air purifiers may not produce measurable health changes in healthy children.
