Table 3 Crude and adjusted estimates of percent change in infection prevalence^a associated with net use and covariates

Covariate	Unadjusted estimate		Adjusted estimate^a
Covariate	% Change (SE)	p value	% Change (SE)	p value
Community net use (10% increase)	6 (2)	0.02	6 (2)	0.01
Proportion of children under 5 using nets (10% increase)	3 (2)	0.12	−4 (4)	0.36
Proportion of population composed of children under 5 (10% increase)	−8 (16)	0.64	−1 (5)	0.97
Proportion of SAC who use nets (10% increase)	5 (2)	0.01	5 (5)	0.33
Average community wealth index (1 unit increase)	−18 (7)	0.01	−7 (4)	0.09
Transmission setting
Low transmission	Ref	–	Ref	–
Moderate transmission	85 (16)	<0.001	76 (16)	<0.001
High transmission	209 (17)	<0.001	192 (19)	<0.001

All models include random effect for EA and account for correlation across surveys using a Toeplitz covariance structure
Adjusted models all include community net use, average community wealth index, season, and transmission setting
