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

We have used quantitative immunoelectronmicroscopy to compare the in situ localization of acid alpha-glucosidase, lysosomal acid phosphatase, beta-hexosaminidase and glucocerebrosidase in intestinal epithelial cells of the human duodenum. Differences between these four lysosomal enzymes were observed with respect to their presence at the apical cell surface. Transport to the apical membrane seems to be a more important intracellular route for lysosomal acid phosphatase and acid alpha-glucosidase than it is for beta-hexosaminidase. The membrane associated lysosomal enzyme glucocerebrosidase is not transported to the microvilli. The studies emphasize that lysosomal enzyme transport pathways are enzyme and cell type specific.
