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

Trillions of bacteria inhabit the mammalian gastrointestinal tract. In the majority of hosts, these symbionts contribute largely to beneficial functions promoting microbe-host homeostasis. However, an increasing number of human diseases is associated with altered microbiota composition and enrichment of certain bacterial species. A well-known example of this is Mucispirillum schaedleri, which has been associated with inflammatory conditions in the intestine. Mucispirillum spp. belong to the phylum Deferribacteres and are prevalent but low abundant members of the rodent, pig and human microbiota. Recently, M. schaedleri was causally linked to the development of Crohn's disease-like colitis in immunodeficient mice. While this study certifies a considerable pathogenic potential, the same organism can also promote health in the immunocompetent host: M. schaedleri protects from Salmonella enterica serovar Typhimurium (S. Tm)-induced colitis by interfering with the expression of the pathogen´s invasion machinery. In this review, we summarize the current knowledge on the mammalian gut symbiont M. schaedleri and its role in intestinal homeostasis and discuss open questions and perspectives for future research.
