Frequencies of Plasmodium falciparum dhps A581G alleles in pooled (A) and individual placental (B) parasite templates. A, Frequencies of dhps A581G allele in pooled parasitemias by study site, study arm, and specimen type. * The sequencing of pooled maternal peripheral parasites from Chikwawa IPTp-SP recipients failed to yield analyzable reads. B, Frequency distribution within individual placental parasitemias of dhps A581G alleles in participants receiving ISTp-DP or IPTp-SP in the Mpemba site. Abbreviations: IPTp-SP, intermittent preventive therapy during pregnancy with sulfadoxine-pyrimethamine; ISTp-DP, intermittent screening during pregnancy and treatment with dihydroartemisinin-piperaquine.
