“This represents a 48% reduction in median 24-h concentrations (p = 0.005).”

Assessing the Impact of Water Filters and Improved Cook Stoves on Drinking Water Quality and Household Air Pollution: A Randomised Controlled Trial in Rwanda (2014). PloS one. Page 7. CKB 6884

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Intervention: Improved cookstoves
Setting: cooking area, RW
Study design: randomised controlled trial in rural Rwanda: households received a water filter and an improved cookstove, with 24-hour fine particulate matter measured in the cooking area of intervention and control households and drinking water quality measured alongside (class 2)
Effect: difference 48
Averaging time: 24 h
Caveat: among intervention households that reported cooking indoors the reduction was 37 % and only borderline significant
