Although not directly comparable due to the different scales, the results across all strategies showed a logarithmic relationship between mean catchment area and proportion of compounds correctly identified (Fig. 4) . Points that are located in the top left corner represent the optimal combination of low mean area (high precision) and a high proportion of people correctly located using that strategy (high accuracy). The results of this analysis suggest that using the location of the nearest primary school as well as the participatory mapping with buffer was the most promising method to geolocate rural health-facility attendees in this rural study setting.
