Rates of new infections by treatment group at day 63. Lost to follow-up are censored at the drop-out time, informative withdrawals are censored at the withdrawal time, patients imputed as recrudescence (day of failure < day 4) are censored at the time of recrudescence, patients with recrudescence detected by PCR are censored at day of failure, patients with not interpretable or missing or not done PCR at failure are censored at day of failure, patients classified as success are censored at the time of day 63 assessment. The number of patients at risk of new infection is reported at weekly visits by treatment group under the Kaplan-Meier curves. A + M, artesunate-mefloquine; DP, dihydroartemisinin-piperaquine.
