Data presented are cumulative, failures up to day 14 of follow-up are also considered in the calculation of day 28 failure rates.

Percentages are rounded to achieve totals of 100%.

CQ, Chloroquine; AQ, amodiaquine; SP, Sulphadoxine-pyrimethamine; AS, artesunate ETF, early treatment failure; LCF, late clinical failure; LPF, late parasitological failure; ACPR, adequate clinical and parasitological response.

* Significant difference to CQ group (P < 0.05); ** Significant difference to CQ and AQ groups (P < 0.05).
