Finding F-1777

“Following intervention, personal CO exposure was lower in the LPG arm (median CO, 0.52 ppm; IQR, 0.20–1.16) and in the improved biomass stove arm (median CO, 0.74 ppm; IQR, 0.33–1.47) as compared with in the control arm (median CO, 0.82 ppm; IQR, 0.37–1.65).”

Structure

Factor: Carbon monoxide (CO)
Intervention: Clean fuels
Setting: personal exposure of pregnant women
Study design: multi-country randomised controlled trial in pregnant women (HAPIN): households were assigned a liquefied petroleum gas stove and fuel, an improved biomass stove, or usual cooking, with personal carbon monoxide and fine particulate matter measured after the intervention (class 2)
Effect: median 0.52
Caveat: a personal exposure of the pregnant women, not a room concentration
