Difference in interleukin 15 (IL-15) concentration in cervicovaginal lavage fluid from women with and those without Schistosoma haematobium infection (A) and women with and those without Schistosoma mansoni infection (B). The median IL-15 value was 62.8 pg/mL in women with S. haematobium infection, compared with 102.9 pg/mL in uninfected women (adjusted P = .0013). There was no significant difference in IL-15 concentrations between women with S. mansoni infection and schistosome- uninfected control women from the same village. The box plot displays median values (dark horizontal bars) and interquartile ranges (boxes), with error bars representing 1.5 times the interquartile range or the minimum/maximum values. Each triangle and square represents the IL-15 level for 1 unique patient in the specified group.
