Temporal and spatial dynamics of adjusted monthly malaria incidence in Ifanadiana, 2014–2017. a Average number of new cases per 1000 population of all ages per month in the most plausible adjusted dataset (orange) and before adjustment (teal). An equivalent plot including only children under five can be found in Additional file 1: Figure S6. b Geographic distribution of malaria, averaged over all months (left), high season months (December to May; center), and low season months (June to November; right). Color gradient represents average monthly malaria incidence per 1000 population. Equivalent plots of spatial distribution in unadjusted health center register data are included in Additional file 1: Figure S4
