  1. IRS = indoor residual spraying; LLIN = long-lasting insecticide net
  2. *OR = odds ratio
  3. #CI = confidence interval
  4. λSmall weighted constant added to cells contributing to the zero cell count in the younger age-group for LLIN#1
  5. a = A total of 28 isofemale lines were tested against three LLINs
  6. b = A total of 30 isofemale lines were exposed to three walls sprayed with bendiocarb (0.1%)
