text_1: Patients with microcytosis and higher erythrocyte count were more resistant to severe malarial anaemia when infected with Plasmodium falciparum.
text_2: This model predicted that children homozygous for alpha(+)-thalassaemia lose less Hb than children of normal genotype for a reduction in erythrocyte count of >1.1 x 10(12)/l as a result of the reduced mean cell Hb in homozygous alpha(+)-thalassaemia.
