Panel A–D shows the posterior mean distribution of PfPR_2–10 by the prediction years of 1969–1989 in Namibia.

Panel F–J shows enlarged maps of the posterior mean distribution of PfPR_2–10 by the prediction years of 1969–1989 in the three intervention regions of Caprivi, Kavango and Ovambo. Panel K–N shows the percentage difference from a reference year of 1969 of the PfPR_2–10 predictions in 1974, 1979, 1984 and 1989. Negative/positive values indicate a decrease/increase in predicted PfPR_2–10. The grey shade represents areas where transmission is unsuitable due to aridity. All maps are at 5×5 km spatial resolution.
