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 mast cells located in the intestinal mucosa of a non-eutherian mammal were studied in comparison with those in the skin of the ear. In the intestinal mucosa, the mast cells exhibited a more variable shape, larger cytoplasmic granules and greater sensitivity to fixatives regarding their staining towards Toluidine Blue. Ultrastructurally, these granules were more heterogeneous but lacked the crystalline content found in granules of skin mast cells; lipid body-like organelles were found only in the mucosa-located mast cells. Histochemically, they differed from skin mast cells by the absence of periodic acid-Schiff (PAS)-positive granules. Unlike the mucosal mast cells of the rat, they fluoresced brilliant yellow after berberine treatment, which is evidence of the presence of heparin.
