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 74-year-old man presented with intestinal obstruction. CT (computed tomography) revealed a 25-mm mass in the proximal jejunum. Double-balloon endoscopy (DBE) identified a smooth, asymmetrically localized mass with oozing and luminal stenosis covered with the mucosa of swollen villi. Small bowel radiography demonstrated jejunal obstruction. Histopathological examination of the resected specimen confirmed moderately differentiated adenocarcinoma arising from ectopic pancreatic tissue of Heinrich type I. Our case suggests that cancer arising from ectopic pancreas should be considered as a candidate diagnosis of a submucosal tumor in the jejunum.
