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

Endo-β-1,6-galactanases hydrolyze β-1,6-linked galactosyl linkages in galactans, yielding β-1,6-linked galacto-oligosaccharides, predominantly galactobiose. Here, we report to our knowledge the first crystal structure of an endo-β-1,6-galactanase, together with its β-1,6-galactobiose-bound complex, revealing the structural basis for substrate recognition by this enzyme. Endo-β-1,6-galactanase from Streptomyces avermitilis (Sa16Gal30A) is a member of glycoside hydrolase family 30 (GH30) subfamily 5. Sa16Gal30A consists of two structural domains: a catalytic (β/α)
