LSTM led Cooking and Pneumonia Study (CAPS) finds no evidence that cleaner burning biomass fuelled cookstoves reduce the risk of pneumonia in young children in rural Malawi

Results from the Liverpool School of Tropical Medicine (LSTM)-led Cooking and Pneumonia Study (CAPS) in Malawi indicate that cooking with cleaner burning biomass-fueled stoves in place of traditional open fires has no effect of the incidence of pneumonia in children under the age of five.

The two year study was the largest of its kind anywhere in the world, with over 10,000 children enrolled across randomised villages in rural Chikhwawa and Chilumba in Malawi. The results, published in the journal, The Lancet today, show that the risk of pneumonia was the same in the under-fives whose families were assigned the cleaner burning biomass-fueled cookstoves as in those whose families continued to cook over traditional open fires. In a secondary safety analysis a marked 42% reduction in the risk of non-serious burns was seen in children in the cookstove group compared to the open fire group...

I don't think these stoves were vented to the outside. This appears to the model used, though it is no longer manufactured.

Better results in women in the past were gotten when venting was used with more conventional stoves, but in a village setting, there could be poor air quality outside where children play.

Pierce County, WA, used to subsidize changes from old wood stoves to new EPA certified models, but quit that after they realized that still would not help air quality much in urban/suburban areas. They would only subsidize changing to non-biomass systems after that.
