Fig. 2From: Single low dose primaquine to reduce gametocyte carriage and Plasmodium falciparum transmission after artemether-lumefantrine in children with asymptomatic infection: a randomised, double-blind, placebo-controlled trialGametocyte prevalences (a) and densities (b) measured by qRT-PCR in children with patent gametocytes on day 0. 95 % confidence intervals are presented in (a). Samples were considered to be gametocyte negative if assigned levels were lower than 0.02 gametocytes per μL. AL = artemether-lumefantrine; 0.25 mg/kg = 0.25 mg/kg primaquine arm; 0.40 mg/kg = 0.40 mg/kg primaquine armBack to article page
