Finding F-0972

“A 1 ppm-year higher cumulative CO exposure was associated with higher risks of developing allergic rhinitis symptoms (OR = 1.09, 95% CI: 1.02–1.18) and allergic conjunctivitis symptoms (OR = 1.11, 95% CI: 1.02–1.21), after adjusting for all covariates”

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Outcome: Conjunctivitis
Population: young children
Setting: home, GT
Study design: prospective cohort in the western highlands of Guatemala: cumulative personal carbon-monoxide exposure of young children in three groups defined by chimney-stove use in the RESPIRE and CRECER studies, against allergic outcomes, skin prick tests and symptoms, adjusted for socio-economic covariates (class 3)
Effect: OR 1.11 (1.02–1.21) per 1 ppm-year of cumulative carbon-monoxide exposure
Caveat: cumulative exposure over years, built partly from proxy measurements in sibling children

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
