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 Results may not be published yet.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.
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

Summary

Researchers are testing whether painting roofs with UV-resistant white paint and teaching heat literacy can lower indoor temperatures and improve health in rural Malaysian communities. About 1,110 adults take part in one of four groups: cool roofs plus education, cool roofs alone, education alone, or neither. Participants wear activity trackers and answer questionnaires over several follow-up visits to track sleep, physical activity, blood sugar, and mood.

What this could mean

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

Active substance
cool roof painting and heat literacy education
What this could lead to
If it works, this could give rural communities a low-cost way to stay cooler during heat waves and may shape heat adaptation programs in similar climates.
What could go wrong
Cool roofs and education may not lower body heat stress enough to change health measures, and results from rural Malaysia may not apply elsewhere. The study measures short-term markers rather than long-term disease outcomes.
