Finding F-0845

“Severe pneumonia with oxygen saturation <90% was associated with COHb (IRR, 0.95; 95% CI, 0.91 to 0.99; P 1⁄4 .011), where higher COHb levels were mildly protective.”

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 0.95 (0.91–0.99)
Caveat: the authors call it mildly protective and note that after correction for the false-discovery rate none of their results stays significant; 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
