Figure 2

Additional incremental impact of outdoor contact toxins (θ μ,pre,o = 0·5) or repellents that are exclusively used outdoors (θ Δ,o = 0·5) or used both indoors and outdoors (θ Δ,i+o = 0·5) when combined with indoor LLINs with contact toxins (θ μ,pre ,i = 0·5), compared with their direct impact as stand-alone intervention strategies. Impact is expressed in terms of the mean relative risk of exposure to residual transmission for the average community member where LLINs are combined with additional products with the above profiles (ψh,combination) compared with when they are applied as a stand-alone measure (ψh,LLINs alone). All products are assumed to confer 50% personal protection (ρo or ρi+o = 0·5) by either repelling or killing half of all mosquitoes that attack them (θ = 0·5). Further details of the model and symbol definitions are available online (See Additional file 4)
