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 recently identified a new class III chitinase from pomegranate seeds (PSC). Interestingly, this new chitinase naturally binds calcium ions with high capacity and low affinity, suggesting that PSC is a Ca-storage protein. Analysis of the amino acid sequence showed that this enzyme is rich in acidic amino acid residues, especially Asp, which are responsible for calcium binding. Different from other known chitinases, PSC is located in the stroma of amyloplasts in pomegranate seeds. Transmission electron microscopy (TEM) analysis indicated that the embryonic cells of pomegranate seeds are rich in calcium ions, most of which are distributed in the stroma and the starch granule of the amyloplasts, consistent with the above idea that PSC is involved in calcium storage, a newly non-defensive function.
