Prevalence of schistosome positive individuals by age.
Prevalence increases with age for all 4 assays.

STH infection status does not affect SWAP-ELISA values.
Comparison of SWAP ELISA values in schistosome negative (top) and schistosome infected (bottom) individuals based on STH infection status. Y-axis scales differ in order to better analyze the schistosome negative individuals. There are no significant difference between SWAP ELISA values based on STH infection status (p = 0.4263 and 0.8868, respectively) with one-way analysis of variance (Kruskal-Wallis ANOVA).

Urine CCA assays are not affected by STH infection status.

SWAP-ELISA values correlate with level of schistosome infection.
Average SWAP-ELISA values for the negative, light, moderate and heavy intensities of infection as determined by average EPG (p<0.001, Kruskal-Wallis ANOVA).
Figure 4.
CCA assay band intensity correlates with level of schistosome infection.
The intensity of the results of the CCA assays are associated with schistosome infection intensity (p<0.0001, Kruskal-Wallis ANOVA), as determined by the Kato-Katz method (EPG).
