Mean difference of haemoglobin level in G6PD deficient and G6PD normal patients receiving primaquine based on the type of malaria. Data of mean difference was presented as g/dL, standard error (SE), and 95% confidence interval of mean difference. Differences in haemoglobin level were measured between day 0 (baseline) and day 7 or 28, depending on the type of infection and study design. Doses of primaquine vary. SE standard error, G6PD Glucose-6-phosphate-dehydrogenase; ^†analysis of study within 7 days of observation; ‡analysis of study within 28 days of observation; *analysis of study with all doses of primaquine included in the study
