a

AL, artemether-lumefantrine; DP, dihydroartemisinin-piperaquine; Z, Zaire; U, Uíge.

b

ETF, early treatment failure; RECR, recrudescence; REIN, reinfection.

c

Multiplicities of infection (MOI) either are the same for day 0 and the day of failure or are reported as day 0 MOI/day of failure MOI.

d

Resistance markers either are the same for day 0 and the day of failure or are reported as day 0/day of failure. wt, wild type.

e

“CN” represents the P. falciparum multidrug resistance gene 1 copy number, and “haplotype” represents the haplotype constructed from mutations N86Y, Y184F, and D1246Y.

f

Shown are the chromosome 10 (Chr 10) SNP at position 688956 and Chr 13 SNP at position 1718319 associated with artemisinin resistance.

g

Molecular data for early treatment failure are available for day 0 only.
