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

Compared to wild-type (WT) mice, schistosome granulomas in Stat6 knockout (KO) mice lacked eosinophils and had Th1 features. Interleukin-4 (IL-4) acts through Stat6 in assisting Th2 cell development. The importance of Stat6 for Th2-cell development within schistosome granulomas had not been explored. Therefore we studied gamma interferon (IFN-gamma), IL-4, and IL-5 production in granulomas from Stat6 KO and WT mice. Dispersed granuloma cells from Stat6 KO and WT mice made similar amounts of IL-4 and IL-5. Only Stat6 KO granuloma cells released IFN-gamma. Granuloma T cells contained most of the IL-4, IL-5, and IFN-gamma mRNA and secreted these cytokines. In Stat6 KO mice, 16.6% of the granuloma cells were CD4(+). Of these, 10.7% stained for IFN-gamma and/or IL-4 by intracytoplasmic flow analysis. Few CD4(-) T cells stained positively. The IL-4-producing T cells did not stain for DX5 or with labeled alpha-GalCer CD1d tetramer, suggesting an absence of NK T cells. Thus, conventional Th cells in Stat6 KO granulomas produce IFN-gamma and Th2 cytokines. Stat6 limits IFN-gamma production but is unnecessary for Th2-cell development or localization within the granuloma.
