Finding F-1716

“In multivariate analysis, current exposure to coal smoke was associated with a 31.7% decrease in FVC, a 42.0% decrease in FEV1, a 7.46% decrease in the FEV1/FVC ratio, and a 23.1% decrease in PEFR in adult residents.”

Structure

Source: Coal
Outcome: Lung function
Setting: home
Study design: cross-sectional study of adult residents: current exposure to coal smoke at home related to lung function in multivariate analysis, with fine particles measured in the kitchens and living rooms of both groups (class 4)
Effect: difference 42.0
Flags: implausible
Caveat: a very large decrease for a cross-sectional comparison, so it should be read as the study's own multivariate estimate and not as a within-person change
