What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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 study investigates whether improving public housing conditions—such as renovations, neighborhood upgrades, and indoor air purifiers—can improve lung health and reduce chronic disease in adults living in Birmingham, Alabama. Participants are residents of four public housing sites, some of which will receive housing and neighborhood improvements, while others will receive air purifiers. The researchers will measure changes in overall health, stress levels, lung function, and indoor air quality over time.

What this could mean

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

Active substance
Indoor air purifier (HEPA/activated carbon filter), housing renovations, neighborhood improvements (green space, sidewalks, social programs)
What this could lead to
If successful, this could show that better housing and cleaner indoor air meaningfully improve lung health and reduce chronic disease burden in vulnerable communities.
What could go wrong
This is a non-randomized study with many variables, so it may be hard to prove which change caused any health improvements. Results may not apply to other populations or settings.
