Changes in transmission intensity, proportion of kelch13 mutations, and parasite clearance rates from 2001 to 2011. Upper graph: Proportion of Plasmodium falciparum–positive cases among children aged <5 years attending clinic within the same study area (left y-axis, data adapted from [25]); Proportion of patients genotyped with a kelch13 mutation associated with parasite clearance half-life (PCt1/2) ≥ 5 hours (right y-axis). Lower graph: The PCt1/2 (medians and interquartile ranges) are plotted. Abbreviation: P. falciparum, Plasmodium falciparum.
