Comparison of the membrane assay to the gold standard with rabbit assay. The difference in the odds of mosquito mortality at 24-h (M24) and 72-h (M72) and blood feeding success (BFS) for resistant Anopheles arabiensis was measured between the gold standard rabbit assay with 100 mosquitoes and the membrane assay with 50 mosquitoes *.
