Fig 3. Sex-prevalence and intensity curves for schistosomiasis.
The bars indicate overall infection prevalence per sex. Lines indicate mean log-transformed infection intensities among positive subjects. A: S. haematobium infection; Sex vs prevalence p = 0.487; infection intensity vs sex p = 0.004*. B: S. mansoni infection; Age vs prevalence p = 0.883; infection intensity vs age p = 0.797. C: Ectopic egg (S. mansoni in urine) infection; Age vs prevalence p = 0.073; infection intensity vs age p = 0.289.
