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

Schistosomiasis is one of the most detrimental neglected tropical diseases. Controlling the spread of this parasitic illness requires effective sanitation, access to chemotherapeutic drugs, and control over populations of the freshwater snails, such as Biomphalaria glabrata, that are essential intermediate hosts for schistosomes. Effectively controlling this disease, while minimising ecological implications of such control, will require an extensive understanding of the immunological interactions between schistosomes and their molluscan intermediate hosts. Here we histologically characterise the clearance of schistosome larvae by snails that exhibit allelic variation at a single genomic region, the Guadeloupe resistance complex. We show that snails with a resistant Guadeloupe resistance complex genotype clear schistosomes within the first 24-48 h, and that this resistance can be transferred to susceptible snails via whole hemolymph but not cell-free plasma. These findings imply that Guadeloupe resistance complex-coded proteins help to coordinate hemocyte-mediated immune responses to schistosome infections in Guadeloupean snails.
