Fig. 3 — Scenario analysis (savannah settings). Impact of varying the number of larvicide applications (horizontal axes) and the interval between applications (in days, vertical axes) on three measures of effectiveness: (i) the proportion of bites averted during the intervention (vertical left-hand panels); (ii) the proportional reduction in DBR (vertical middle panels); (iii) the time taken to return to pre-intervention baseline DBRs (vertical right-hand panels). In a, b and c larvicidal efficacy is 99%. In d, e and f the results for 93% efficacy are presented. In g, h and i larvicidal efficacy is 70%. (For precise definitions of the effectiveness measurements see section on Scenario analysis in the main text. Equivalent results for the forest settings are presented in Additional file 1, Results of scenario analysis)
