  1. aEstimated from [19], Tables 2 and 3
  2. bConservative or neutral assumptions
  3. cEstimated from [20]
  4. dNo definitive data available. A non-zero value was chosen and the full range of deflection values explored in Figs. 3 and 4
  5. eSnetselaar et al. pers. comm
  6. fIntentionally conservative estimate of exiting mortality
  7. gDeflection and mortality were estimated as total mortality of 40 % based on [21] Tables 1 and 2, [22], Table 2d (44–47 % survival of fed mosquitoes with treated nets vs 93 % for controls, and 38 vs. 78 % of unfed), and [23] for reduced entry rate and slightly elevated exit rate, plus estimates of mortality in Tables 2 and 5
  8. h[24] Anopheles gambiae house exiting rate
  9. iEstimated from [25]
  10. jWithin range from [26] Tables 1 and 2, and [25]
