Fig. 4From: Comparison of cone bioassay estimates at two laboratories with different Anopheles mosquitoes for quality assurance of pyrethroid insecticide-treated netsBland-Altman Plot showing the mean difference (y axis) plotted against the average value from both sites (x) A KD60 and B M24. For KD60 Mean difference (limits of agreement) was 15.5 (−25.4–56.5) and for M24 Mean difference (limits of agreement) was −17.0 (−61.4–27.3). At lower mean values of knockdown, the agreement between the two testing facilities was lower than at higher mean values of knockdown but there was a consistent difference in mean difference in M24 measured at each testing facilityBack to article page
