Adjusted associations between house construction and malaria prevalence by rapid diagnostic test in the southern Zambia study site from 2008 to 2012

Wall material	Roof material	No. of participants (% total)	Malaria prevalence, % (n)	Adjusted OR	95% CI	P value
Fired brick/cement	Iron sheet/corrugated tin	849 (30)	1.4 (12)	0.26	0.09–0.73	0.01
Fired brick/cement	Grass	1,825 (65)	1.6 (30)	0.22	0.09–0.52	< 0.01

CI = confidence interval; OR = odds ratio. Generalized estimating equations logistic regression model adjusted for transmission season, clustering by house, distance to third-order stream, participant age, participant gender, participant bed net use, prior indoor residual spraying, head of household level of education, and homestead with > 1 contemporaneous case.
