  1. aChi(p) is the p-value of the Chi-square test of homogeneity
  2. bAcerKis, AgRR5, and Kisumu are different populations of An. gambiae exposed to bendiocarb, Fig. 2a (data from [3])
  3. cDZOU and KIS are different populations of An. gambiae exposed to temephos, Fig. 2b (unpublished data)
  4. For each insecticide, Kisumu and KIS populations respectively have the lowest LD50 and were used as the references to compute the respective resistance ratios (RR50)
