Prevalence of the Pfdhps-431V mutation in Nigeria, and bordering countries by upper administrative unit, using published studies of surveys done between 2007 and 2021 (for Nigeria: 25 surveys from 16 studies; Ntotal samples = 2262, and for neighbouring countries: 32 surveys from 27 studies; Ntotal samples = 3248). This is calculated as the number with the mutation among the number of samples determined at that position. Proportions were weighed by each study’s sample size for regions where more than one study was conducted
