Panel A–D shows the posterior mean distribution of PfPR2–10 by the prediction years of 1969–1989 in Namibia.

Panel F–J shows enlarged maps of the posterior mean distribution of PfPR2–10 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 PfPR2–10 predictions in 1974, 1979, 1984 and 1989. Negative/positive values indicate a decrease/increase in predicted PfPR2–10. The grey shade represents areas where transmission is unsuitable due to aridity. All maps are at 5×5 km spatial resolution.
