Structure

Source
Tobacco smoke (secondhand smoke)
Factor
Particulate matter (PM₂.₅ and PM₁₀)
Setting
home
Study design
study of particle concentrations in inner-city homes: two-week average indoor and outdoor fine particles measured in homes across several cities, with a multivariate model separating the outdoor contribution from the indoor sources (class 4)
Effect
difference 37
Caveat
a two-week average, so short peaks are averaged away
