Figure 2. Drop in Haemoglobin Level during the Malaria Season according to HbAS, G6PD Deficiency, and Haptoglobin Genotype.

Figure 2

Haemoglobin levels at the start and end of the malaria season are shown by haptoglobin genotype ( Hp 2/2 versus Hp 1/1 and Hp 1/2 combined), HbAS compared to HbAA and G6PD (A type) deficiency, wild-type, heterozygotes, and homozygotes/hemizygotes. Error bars denote standard error of the mean.
