Six- and 12-month time course of developmental quotient (DQ) scores for treated S. haematobium positive children.

Scatterplots show DQ scores for a) children positive and treated for S. haematobium infection at baseline (n = 29), b) children present at S1 survey (6 months later) and tested negative for S. haematobium infection (n = 29), and c) children present at S2 survey (12 months later) who remained negative for S. haematobium infection (n = 18). Dotted lines represent the mean reference average for DQ (100). p-values indicate statistical tests for either a one sample t-test or Wilcoxon sign test (based on normality) comparing to the hypothetical mean of 100. Solid lines = mean.
