Finding F-1717

“The reduction in the risk of COPD was unequivocal after the fuel and ventilation improvements, with an odds ratio of 0.28 (95% CI, 0.11 to 0.73) for both improvements.”

Structure

Outcome: Chronic obstructive pulmonary disease (COPD)
Intervention: Ventilation
Setting: kitchen
Study design: cohort study of a fuel and ventilation intervention: households replacing biomass with biogas and improving kitchen ventilation followed for lung function decline and for chronic obstructive pulmonary disease (class 3)
Effect: OR 0.28 (0.11–0.73)
Caveat: both improvements together — replacing biomass with biogas and improving the kitchen ventilation — so the two cannot be separated
