Fig 2. Predicted prevalence of Schistosoma mansoni infection in Rwandan boys aged 5–9 years, estimated using three different diagnostic methods: Kato-Katz (Panel A), CCA with trace as positive (Panel B), and CCA with trace as negative (Panel C).

Predictions were generated using separate geostatistical models to account for possible discrepancies in diagnostic performance and estimates of geographical endemicity. Refer to S3 Fig in Supporting Information for names of geographical districts. This figure was produced in ArcMap 10.4 (ESRI, Redlands, CA) using a shapefile representing Rwanda’s current administrative units (obtained from the geographic data warehouse DIVA GIS (www.diva-gis.org/Data)). CCA; Circulating Cathodic Antigen.
