Finding F-0976

“Overall, CO exposure was 39% lower in the stove group than in the open-fire group, with mean (± SD) 48-hr values of 4.1 ± 3.2 ppm and 2.5 ± 2.5 ppm, respectively (p = 0.0003).”

Structure

Source: Wood
Factor: Carbon monoxide (CO)
Intervention: Improved cookstoves
Population: pregnant women and their newborns
Setting: home, GT
Study design: analysis inside RESPIRE, a randomised trial in rural Guatemala: pregnant women were given a chimney stove or kept an open fire, with 48-hour personal carbon monoxide measured in pregnancy and newborn birth weight measured within 48 hours of birth, adjusted for maternal height, gravidity, blood pressure and season (class 3)
Effect: mean 4.1
Averaging time: 48 h
Flags: source-inconsistent
Caveat: the sentence says carbon monoxide was 39 % lower in the stove group but then lists 4.1 before 2.5 'respectively', which puts the higher value on the stove group - the order in the source contradicts its own statement, so the group is not assigned here
