Fig. 4From: The haematological consequences of Plasmodium vivax malaria after chloroquine treatment with and without primaquine: a WorldWide Antimalarial Resistance Network systematic review and individual patient data meta-analysisFractional change in haemoglobin between baseline and day 7 following a chloroquine and b chloroquine plus primaquine. In patients treated with chloroquine alone, 608 had normal G6PD status and 588 had unknown G6PD status. In patients treated with chloroquine plus primaquine, 389 had normal G6PD status and 150 had unknown G6PD status. The open circle represents the single patient with a clinically significant fall > 25% to < 7 g/dL at day 7 (female patient with normal G6PD status). The dashed orange line represents a fractional fall of 25%Back to article page
