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

This study focuses on ancient proteins preserved as carbonized food residues on pottery from East Asian archaeological sites associated with plant use. Food residues on pottery vessels were carbonized hundreds to thousands of years ago when plant and animal materials were heated; so, only trace amounts of proteins and other biomolecules are expected to remain. Paleoproteomic analysis showed that many peptides derived from cupin superfamily proteins of plant origin, such as the glycinin proteins of the genus
