Finding F-1785

“The likelihood that a child’s bedroom met the WHO indoor air quality standard on a given day increased such that the baseline versus post-baseline odds ratio (OR) of maintaining indoor PM2.5 levels below the WHO guideline was 2.38 times larger for participants who received the intervention.”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Intervention: Health education
Setting: bedroom
Study design: trial of a smoke-free home intervention with air quality feedback: fine particulate matter in the child's bedroom monitored continuously, with the odds of meeting the World Health Organization guideline compared between baseline and post-baseline phases in intervention and control participants (class 2)
Effect: OR 2.38
Caveat: the outcome is the chance that a day met the guideline, not a concentration
