Finding F-1743

“The geometric mean (± geometric SD) 24-h indoor PM2.5 concentration in biomass using homes was significantly greater than in non-biomass using homes (455 ± 2.4 vs. 101 ± 2.0 μg/m3, p <0.001), although there was no significant difference in outdoor air pollution between biomass and non-biomass using homes (129 ± 2.7 vs. 115 ± 2.5 μg/m3, p = 0.249).”

Structure

Source: Biomass fuel
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: home, NP
Study design: cross-sectional study of rural and urban Nepalese adults: 24-hour indoor fine particulate matter and carbon monoxide measured in biomass-using and non-biomass-using homes, with respiratory symptoms recorded by questionnaire (class 4)
Effect: median 455
Averaging time: 24 h
Caveat: a geometric mean recorded under measure median, with the geometric standard deviation in the dispersion field
