(a) Map showing the spatial location of the studies included in the modelling of K13 prevalence. The size of the marker is proportional to the number of patients in the study and the colour of the marker denotes the observed K13 marker prevalence. National shapefiles were obtained from the Malaria Atlas Project (MAP; https://malariaatlas.org/) under their open access policy (https://malariaatlas.org/open-access-policy/) and no changes were made. (b) Number of studies each year since 2000, broken down by country. (c) Temporal trends in country level K13 prevalence data since 2000, where the number of patients is denoted by the size of the circles.
