1 Proportion of among-area variance of total spatial variance measured on a logit scale (i.e. σj(i)/(σj(i)+ θj(i)k(i), see methods). Posterior median estimated from model does not exactly correspond proportion calculated from posterior medians of individual variances.

2 Relative chance of posterior median of variance components from bed-net adjusted to non-adjusted model.

3 Sum of posterior medians of among-area and village-within-area variance components (i.e. σj(i)+ θj(i)k(i))

Pf = P. falciparum, Pv = P. vivax, Pm = P. malariae, Po = P. ovale
