  1. NB: The numbers in brackets represent prevalences.
  2. Bold data indicate the mean mf and nodule prevalence; and mean intensity of infection in children and adults for each river basin.
  3. The total line (bold) indicates the overall mf and nodule prevalence and intensity of infection for each river basin.
