Structure

Source: Solid fuel
Outcome: Chronic obstructive pulmonary disease (COPD)
Setting: home, CN
Study design: prospective cohort of Chinese adults: cooking and heating fuel recorded at baseline and at resurveys, with incident chronic obstructive pulmonary disease ascertained through linked health records over a long follow-up (class 3)
Effect: HR 1.34 (1.18–1.53)
Caveat: duration of use, not intensity; for cooking the association with duration was null in the fully adjusted model
