Included village fixed effects and controlled for household characteristics (mosquito nets, flush toilet, improved source of drinking water, house ownership, health insurance) and individual member characteristics (age and sex)
In A, we used a subsample of villages that were in both baseline and endline household surveys. In B and C, we used a subsample of villages retained after Coarsened Exact Matching. In C, we applied weights generated from Coarsened Exact Matching using village-level data matched on age and source of drinking water
