Finding F-0844

“We found no evidence of an association between exposure to CO (incident rate ratio, 1.0; 95% CI, 0.967 to 1.014; P 1⁄4 .53) or carboxyhemoglobin (incident rate ratio, 1.00; 95% CI, 0.993 to 1.003; P 1⁄4 .41) in children who experienced pneumonia vs those who did not.”

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Outcome: Pneumonia
Population: children under 5 years
Setting: home, MW
Study design: longitudinal analysis inside the Cooking and Pneumonia Study, a cluster-randomised trial of cleaner-burning biomass cookstoves in rural Malawi: repeated 24-hour personal carbon monoxide (5521 measurements) and carboxyhaemoglobin (4065 measurements) in children under five against pneumonia episodes, with mixed models adjusted for time, age, sex and smokers in the household (class 3)
Effect: RR 1.00 (0.993–1.003)
Sample: 4065 measurements
Flags: ci-includes-1
Caveat: printed as an incidence rate ratio, recorded under measure RR; the exposure is the biomarker, not a concentration; the text layer prints the equals sign of the p-value as the fraction 1⁄4, which is why the digits 1 and 4 appear among the numbers of the sentence
