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

Bacterial adherence to the intestinal epithelium plays a role in niche establishment in the gut lumen. Through sampling natural populations of Caenorhabditis, we discovered several bacterial species that adhere to the intestinal epithelium via polar, intimate association, best described as attachment. These bacteria had varying effects on host fitness and physiology, with one species having negative effects, and the others exhibiting neutral effects. These bacteria can actively divide in the gut lumen, either replicating throughout the gut simultaneously or anteroposteriorly. In competition assays, animals pre-colonized with an attaching commensal bacteria reduced colonization by the pathogenic bacteria, but this effect was not seen when animals were colonized by both species simultaneously. Regardless of the colonization paradigm, populations exposed to both bacteria showed a near-identical mitigation of the pathogenic effects. Altogether, these strains illustrate the capacity of microbiome bacteria to attach, replicate, and establish a niche across the entire intestinal lumen.
