Table 3 Comparison of median antibody levels of people with and without recent history of malaria and between the sexes (Group A- People with no history of disease within past 10 years, Group B-People with history of malaria disease within past 10 years) 293 individuals who stated ‘did not remember’ having a malaria attack were excluded in this specific analysis

From: Genetic polymorphisms associated with anti-malarial antibody levels in a low and unstable malaria transmission area in southern Sri Lanka
