Figure 12From: Importance of factors determining the effective lifetime of a mass, long-lasting, insecticidal net distribution: a sensitivity analysisDistribution of the number of holes after seven years, depending on holeRate sigma. The black line represents a normalised outline histogram showing the density function of the number of holes as counted by Tami and colleagues [29] in 100 nets. The coloured lines represent the normalised histogram mid-points of the number of holes in simulated nets depending on the holeRate sigma, which is varied over 0.6 (green), 0.8 (blue) and 1.0 (red), with a constant holeRate mean (see above) of 1.8.Back to article page
