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

The transforming growth factor beta (TGF-beta) family controls an extremely wide range of biological activities, such as the growth and differentiation of cells, and immunological events against infectious agents. Although TGF-beta homologs appear to be widely present in metazoan animals, studies of parasite-derived molecules are relatively few. Using antibodies against anti-mouse TGF-beta1, -beta2, and -beta3, we show the expression of TGF-beta-like molecules in Schistosoma japonicum cercariae, schistosomula, eggs and adult worms. Intense immunoreactivity was found on the surface of free-living cercarial bodies. In transverse sections of cercariae, the molecules were localized in the tegument and subtegumental cells, and the number and distribution of producing cells significantly differed with each antibody. In the skin-migrating stage, the expression in the tegumental surface gradually decreased and became almost negative within 48 h of exposure. In adult worms and eggs, the reactivity was found in subtegumental cells and in cells of a tubular structure, respectively. In western blot analysis, the detection of conventional TGF-beta molecules failed. The expression of TGF-beta-like molecules was distinctly regulated at each developmental stage.
