Fig 4. Antibody responses to schistosome worm antigen.

Boxes in white represent uninfected children, grey represent Sm infected children. Boxes and whiskers show interquartile ranges and minimum and maximum values with horizontal lines representing medians. Participants in the Sm infected group were treated with praziquantel and albendazole twice between day 28 and day 56. P values for statistically significant differences in SWA-specific antibody responses between the groups were 0.0060 for IgG, 0.0136 for IgG1 and 0.0004 for IgG4. Abbreviations: SWA, schistosome worm antigen; Sm, Schistosoma mansoni
