Table 3 Contingency analysis for cone bioassays conducted in IHI and PNGIMR to classify the n = 20 ITNs (mean value of 5 net pieces from each ITN) into ‘pass’ and ‘fail’ categories based on mean values for M24 and KD60, using the WHO bioefficacy criteria and the inherent lower CI of the per-protocol cone bioassay as threshold for pass or fail
