Finding F-1700

“Compared with long-term clean fuel users, the fully adjusted ORs were 2.07 (95%CI: 1.37–3.13) for long-term coal users, 1.12 (95% CI: 0.72–1.76) for long-term wood users, and 0.98 (95% CI: 0.55–1.74) for those who used mixed solid fuels to cook.”

Structure

Source: Coal
Outcome: Breast cancer
Setting: kitchen
Study design: case-control study of breast cancer: the household cooking fuel over the long term related to breast cancer risk, with a separate group of women who switched from solid to clean fuels, fully adjusted (class 4)
Effect: OR 2.07 (1.37–3.13)
Caveat: the study says the association is stronger among coal users than among wood users
