Median haemoglobin (g/dL) concentrations over time, by treatment arm (artemether–lumefantrine plus primaquine (solid lines) and artemether–lumefantrine alone (No Primaquine—dashed lines)) and G6PD status (G6PD normal (B or A+ variant—black lines) and G6PD deficient (A− variant—grey lines) with the arrow indicating day 3 when randomization and primaquine treatment occurred. G6PD: glucose-6-phosphate dehydrogenase
