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

Expression of bioactive peptides requires several modifications of the primary translation product. Gastrin, a vertebrate gut hormone, occurs in multiple forms, including a bioactive fragment of the predominant gastrin-17. Gastrin-17 is, however, without known cleavage sites. In order to identify the new site, we therefore isolated, from antral mucosa, fragments of gastrin-34 and -17 monitored by monospecific immunoassays. After three steps of reverse-phase chromatography, the short gastrins were identified as hepta-, hexa- and pentapeptide amides. By far the most abundant of these was tyrosine O-sulfated gastrin-6. The near complete sulfation contrasts with the larger gastrins, of which only half are sulfated. The longest N-terminal fragment of gastrin-34 was a hexadecapeptide without complementarity to the short gastrins. Instead, the predominant N-terminal fragment of gastrin-17 was the decapeptide complementary to gastrin-7. Therefore the novel processing site is the Glu10-Ala11 bond that follows a poly(Glu6-10) sequence. Moreover, gastrin-7 is apparently trimmed, with subsequent accumulation of sulfated gastrin-6. Consequently, O-sulfated tyrosine ensures production of a new hormone which stimulates gastric acid secretion as potently as gastrin-17.
