^aDegrees of freedom.

^bModels fitted separately to species-specific counts per household.

^cDifference between the (residual) deviance of the model with all covariates and the model without the covariate in question [46].

^dRounded to 2 significant figures.

^eCalculated assuming that, under the null hypothesis (of no statistically significant association between the covariate and the numbers of mosquitoes per household), ∆Dev is χ² distributed with the indicated degrees of freedom [71].

^fIncluded as a 4th order polynomial distributed lag term yielding 5 degrees of freedom.
