Plus-minus values are means ±SD. There were no significant differences at baseline among the treatment groups.
Symptomatic malaria was defined as any of the following: fever (axillary temperature, ≥37.5°C) at baseline with parasitemia of any density; a parasite count of more than 2000 per cubic millimeter, regardless of symptoms; or at least three of the following symptoms — fever in the previous 24 hours, weakness or fatigue, muscle or joint aches, headache, or convulsion — with parasitemia of any density.
Symptoms included fever in the previous 24 hours, weakness or fatigue, muscle or joint aches, or headache.
One woman in the amodiaquine-artesunate group was included in the trial during the first trimester of pregnancy.
Women were provided with an insecticide-treated bed net at the start of the trial.
