Scatterplot comparing the mean of developmental quotient (DQ) scores to the expected mean reference average for the six subscales.

Graph shows baseline DQ scores for a) children positive for S. haematobium infection, and b) children negative for S. haematobium infection. Dotted lines represent the mean reference average for DQ (100) [19]. p-values indicate statistical tests for the scores of the children compared to the reference mean of 100. Solid lines = mean.
