Dependence of the population-wide mean proportion of human exposure occurring outdoors with (Ω = N) and without (Ω = 0) 80 % bed net usage upon the proportion occurring indoors in the absence of any nets, for a vector population with the same ability as Anopheles arabiensis to avoid fatal contact with LLINs or IRS after entering houses [16–19], so that the insecticide treatment status of the net is irrelevant
