Illustration of the sigmoid relationship between the nearest discordant household and the effective coverage for the SolarMal trial in grey. In black, the sigmoid curve for \(\hat{\mathcal {R}}_{ijk}\) that approximates the effective coverage is illustrated. To increase the readability, only households within 2Â km of the nearest discordant household are plotted on the x-axis
