Data analysis
REGRESSION
The nightly indoor vector density was calculated at the household level for each of the mosquito collection methods (HLCs, PSCs, and CDC light traps), by dividing the total number of For comparison of mosquito density between collection methods, mixed effect generalised linear model with a negative binomial distribution was used for mosquito density, adjusting for study district (Cove, Ouinhi and Zaganando) as a fixed effect and including study arm as a fixed effect in the post-net distribution data. Cluster was included as a random effect in all models, with collection round also included as a random effect in post-net distribution models. A similar strategy was used with a logistic regression model for SR. Vector density and SR were compared between collection methods using HLCs as the reference.For comparison of mosquito density and EIR between study arms, mixed effect generalized linear models with a negative binomial distribution, with collection round and cluster included as random effects were used. A mixed effect logistic regression model, with collection round and cluster included as random effects, was used to compare SR. Each collection method was assessed separately.All data analyses were performed using the Stata 15.0 (Stata Corp., College Station, TX) software.
