^*CI = confidence interval; CQ = chloroquine; SP = sulfadoxine-pyrimethamine; AQ = amodiaquine; MQ = mefloquine; AS = artesunate; PQ = primaquine. Superscript letters that are not repeated among the treatments show statistically significant differences by the log-rank test or Breslov test.

^†Parasite mean survival time obtained by using Kaplan-Meier analysis.

^‡Arithmetic mean in days taken for parasites to disappear.
