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

A substance from Taenia solium metacestodes that decreases lymphocyte proliferation induced by concanavalin A was isolated. The molecular weight of this substance was estimated to be slightly more than 1,450 Da. Crude metacestode factor was fractionated through a Bio-gel P-6 column. Peak 1 showed suppressive activity. After incubation with RNase the substance lost its activity. Incubation of this material with trypsin or papain increased its suppressive activity. It was stable at boiling temperature for 10 min. The incubation of this substance with murine macrophages had no effect on [3H]-thymidine uptake by cocultured fresh splenic lymphocytes stimulated with concanavalin A. Conversely, cocultures of lymphocytes pretreated with the substance and fresh splenic lymphocytes showed a decreased incorporation of [3H]-thymidine. These results suggest that this substance is a RNA-peptide molecule whose RNA moiety accounts for its suppressive activity. The findings also suggest that in vivo the factor may be a modulator of the immune response.
