Finding F-1689

“Compared with clean fuel use, coal use was associated with a significantly higher risk of cognitive decline (HR = 1.249, 95% CI: 1.061–1.470), whereas biomass fuel use was not (HR = 1.062, 95% CI: 0.944–1.194).”

Structure

Source: Coal
Outcome: Cognitive dysfunction
Setting: home, CN
Study design: prospective cohort of older adults: the household cooking fuel related to cognitive decline over follow-up, with social engagement tested as a modifier (class 3)
Effect: HR 1.249 (1.061–1.470)
Caveat: the same sentence puts biomass fuel use at 1.062 (95% CI 0.944–1.194), which is not significant
