Structure

Source: Coal
Outcome: Chronic bronchitis
Setting: home, CN
Study design: repeat cross-sectional study of the same districts ten years apart: the change in the share of households cooking with coal related to the change in the prevalence of asthma and chronic bronchitis, adjusted for covariates (class 4)
Effect: difference 19.0 (0.96–37.04) per 1 % %
Caveat: men only; the same sentence reports a 1.86% (0.69–3.04%) increase in the prevalence of asthma among women over the same change
