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.
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
L-Arabinofuranosides with β-linkages are present in several plant molecules, such as arabinogalactan proteins (AGPs), extensin, arabinan, and rhamnogalacturonan-II. We previously characterized a β-L-arabinofuranosidase from Bifidobacterium longum subsp. longum JCM 1217, Bll1HypBA1, which was found to belong to the glycoside hydrolase (GH) family 127. This strain encodes two GH127 genes and two GH146 genes. In the present study, we characterized a GH146 β-L-arabinofuranosidase, Bll3HypBA1 (BLLJ_1848), which was found to constitute a gene cluster with AGP-degrading enzymes. This recombinant enzyme degraded AGPs and arabinan, which contain Araf-β1,3-Araf structures. In addition, the recombinant enzyme hydrolyzed oligosaccharides containing Araf-β1,3-Araf structures but not those containing Araf-β1,2-Araf and Araf-β1,5-Araf structures. The crystal structures of Bll3HypBA1 were determined at resolutions up to 1.7 Å. The monomeric structure of Bll3HypBA1 comprised a catalytic (α/α)
