Figure 1From: Ascaris co-infection does not alter malaria-induced anaemia in a cohort of Nigerian preschool childrenChange in the average haemoglobin levels of children who were infected with malaria (black line, circular symbols), Ascaris (grey lines open symbols) or co-infected with both parasites (black line, star symbols) over time. Children with no detectable infection of either parasite (grey line, closed symbols) are shown for comparison. Symbols show the mean haemoglobin levels and the error bars represent the standard error of the mean.Back to article page
