LLIN = long-lasting insecticidal net.
* “Proportion of the population with access to an LLIN” was calculated using the assumption that each LLIN a household owned provided access to up to two household members, as recommended by the Roll Back Malaria Measurement and Evaluation Reference Group.10
† Net condition was evaluated by the study team and guided by comparison to images.
