Overall relationship between haemoglobin concentrations on admission and outcomes in 6451 adults and children with severe falciparum malaria studied in Africa and Asia between 1980 and 2015 who were admitted with a parasite density of > 10,000/μL. Below 5 g/dL (vertical blue dashed line) anaemia itself was a criterion for severe malaria. Inset is shown this same relationship in the subgroup of 2729 patients with cerebral malaria and the same parasitaemia range
