Figure 1 Kaplan-Meier survival curves of PCR-corrected efficacy of dihydroartemisin-piperaquine by (A) study site, (B) crt mutation status, and (C) plasmepsin-2 and plasmepsin-3 amplification status Other crt alleles indicate parasites carrying no mutations at positions 93, 97, 145, 218, 343, and 353 of the crt gene. Infections caused by parasites with a Met343Ile or Gly353Val crt mutation were too scarce to be included in survival curves by crt mutation status.

Figure 2 kelch13 mutation status, plasmepsin2/3 amplification status, and crt mutation status by site and country in the TRACI and TRACII trials (A) KelchX mutation status indicates parasites with a kelch13 mutation other than Cys580Tyr. (B) Single amplification status indicates parasites without a plasmepsin-2 and plasmepsin-3 amplification. (C) Other crt alleles indicate parasites carrying no mutations at positions 93, 97, 145, 218, 343, and 353 of the crt gene.
