Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Population: women and young children
Setting: kitchen, NP (March 2010 to October 2011)
Study design: measurement and estimation study inside the Nepal Cookstove Intervention Trial Phase I, southern Nepal: continuous daily PM2.5 and carbon monoxide in the area near the stove in about 3000 households with traditional open-burning mud stoves, March 2010 to October 2011, summarised in four metrics with mixed models (class 4)
Averaging time: 24 h
Caveat: a stated direction with the thresholds in the comparator; sibling row carries PM2.5
