1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

In schistosomiasis, the severity of CD4(+) T-cell-mediated hepatic granulomatous inflammation against parasite eggs varies considerably in humans and among mouse strains. In C57BL/6 mice, pronounced exacerbation of immunopathology induced by immunization with schistosome egg Ag in CFA (SEA/CFA) substantially recapitulates the natural high pathology seen in CBA mice; both are associated with a significant elevation of Th17- and Th1-cell-derived proinflammatory cytokines. We now investigated the relative contribution of the effector cytokines IL-17 and IFN-γ in pathology development of 7 wk-infected, SEA/CFA-immunized, IL-17(-/-) , IFN-γ(-/-) , and IL-17/IFN-γ(-/-) mice. In IL-17(-/-) mice there was significant reduction of immunopathology despite increased levels of IFN-γ, whereas in IFN-γ(-/-) mice, markedly exacerbated immunopathology correlated with an increase in IL-17. In IL-17/IFN-γ(-/-) mice, complete resistance to SEA/CFA-induced disease exacerbation was associated with a reduction in IL-23p19, IL-1β, CXCL1 and iNOS, and with an increase in IL-5, IL-10 and Relmα. IL-17 and IFN-γ were derived from distinct CD4(+) T cells in which production of each cytokine was suppressed by the other. Our results indicate that severe immunopathology in murine schistosomiasis is mainly driven by IL-17 and regulated by IFN-γ; however, in the absence of IL-17, IFN-γ is capable of exerting a limited, yet significant, pathogenic function.
