Average level of control over the 12-year duration of the simulation, assuming no pyrethroid resistance, for LLINs with a pyrethroid and a different partner insecticide (NEW New AI 1 or 2, PPF  Pyriproxyfen, CHL Chlorfenapyr, PBO Piperonyl butoxide, and–= No partner, i.e. the solo-use of pyrethroid) under different optimality criteria as labelled: A the baseline where both insecticides are used at their solo loadings (BL), B the cheapest bed net that satisfies the WHO requirements (CW), and C the global optimum that maximizes the vector control (MC)
