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

Xenin is a regulatory peptide first isolated from the human gastric mucosa. Using an open-access protein database MEDLINE (33 million molecules; 11 billion amino acid residues) and our original computer program, we conducted a search for the xenin motifs in the primary structure of proteins across almost the entire taxonomic range of evolution. Motifs with 40% homology to human xenin are already present in prokaryotes. Homology reaches 84-96% in single-cell algae and plants, becoming complete since bony fishes. We suppose that this regulatory peptide is more ancient and significant than is usually thought.
