Levels of <i>Schistosoma</i>-induced cytokine responses in 72 h whole blood cultures (n = 200).

<p>Blood samples from one individual were divided into five and stimulated with <i>Schistosoma</i> antigens (SEAm, SEAh, AWAm, or AWAh), and with medium only (negative control; see <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0003080#s2" target="_blank">Materials and Methods</a>).</p>a<p>Crude cytokine levels are reported. IQR: Interquartile range (Tukey's hinges).</p>b<p>Wilcoxon Signed Rank test comparing <i>S. mansoni</i>- and <i>S. haematobium</i>-induced cytokine levels within individuals (either for SEA or AWA).</p>c<p><i>Schistosoma</i> egg antigen.</p>d<p>Adult worm antigen.
