Finding F-0787

“Mean COHgB levels did not correlate with overall maximum CO exposures (Spearman’s ρ = 0.03, p = 0.32), maximum 15-min (Spearman’s ρ = 0.02, p = 0.45), maximum 30-min (Spearman’s ρ = 0.21, p = 0.42), maximum 60-min (Spearman’s ρ = 0.03, p = 0.21) or maximum 90-min exposures (Spearman’s ρ = 0.01, p = 0.58).”

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Population: children under 5 years
Setting: home, MW
Study design: cross-sectional assessment at recruitment to the Cooking and Pneumonia Study, a cluster-randomised trial of cleaner-burning biomass cookstoves in rural Malawi: 48-hour personal carbon-monoxide monitoring of 1928 children under five with carboxyhaemoglobin measured in 1520 of them, against household characteristics and cooking practices from questionnaires (class 4)
Effect: other 0.03
Averaging time: maximum 60-min
Sample: 1520 children
Caveat: a Spearman correlation coefficient, recorded under measure other; none of the five windows correlated with the biomarker
