*Model I assessed independent risk factors in all 14,663 participants (in 3,353 households owning nets). Model II assessed effect of household women's knowledge and school attendance in 12,803 participants (in 2,701 of these households where women of reproductive age completed malaria knowledge questionnaire) adjusting for the effects of independent risk factors from model I.
**Test for interaction between malaria knowledge and school attendance did not reveal any statistically significant effects (Wald Test p-value = 0.781)
