Data are correlation coefficient ± standard error. The asymptotic standard error of a given correlation was estimated by using a second-order Taylor series expansion and replacing all correlation parameters with their respective estimates. Correlations were assessed for all available pair types. Results from saturated models and adjustments were individual risk factors (bed net, hunting, night in the bush, age, sex, and latrine) and environmental variables (road, main river, stream, dry creek, holes, and slate), with a household random effect.
