a Stove types are upesi jiko (ceramic-lined cookstoves) vs. three-stone stoves (traditional firepits with surrounding stones). Household data on stove type were linked to demographic and socioeconomic data for 158 (20.9%) of 757 households with upesi jiko and a random sample of 1,782 households with three-stone stoves.

b P-values are for χ2 tests of association between stove type and demographic and socioeconomic factors.

c Primary caregiver of children in the household. Age and education categorized based on quartiles and the approximate median, respectively. Data were missing for 667 (88.1%) households with upesi jiko and 435 (24.4%) households with three-stone stoves.

d A principal component analysis of household assets (e.g., household goods, building structure) was used to create quintiles of socioeconomic status (SES) among NICHE participant households. SES data were missing for 634 (83.8%) households with upesi jiko and 39 (2.2%) households with three-stone stoves.
