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
introductionIn responses to antibiotics exposure, gut dysbiosis is a risk factor not only for pathogen infection but also for facilitating pathobiont expansion, resulting in increased inflammatory responses in the gut and distant organs. However, how this process is regulated has not been fully elucidated.
objectivesIn this study, we investigated the role of sialic acid, a host-derived carbohydrate, in the pathogenesis of gut dysbiosis-derived inflammation in distant organs.
methodsAmpicillin (Amp)-induced gut dysbiotic mice were treated with N-glycolylneuraminic acid (Neu5Gc) and N-acetylneuraminic acid (Neu5Ac) for three weeks to assess the role of sialic acids in mastitis. The underlying mechanism by which sialic acids regulate mastitis was explored using 16S rRNA sequencing, transcriptomics and employed multiple molecular approaches.
resultsAdministration of Neu5Ac and Neu5Gc exacerbated gut dysbiosis-induced mastitis and systemic inflammation. The gut dysbiosis caused by Amp was also aggravated by sialic acid. Notably, increased Enterococcus expansion, which was positively correlated with inflammatory markers, was observed in both Neu5Ac- and Neu5Gc-treated gut dysbiotic mice. Treatment of mice with Enterococcus cecorum (E. cecorum) aggravated gut dysbiosis-induced mastitis. Mechanically, sialic acid-facilitated E. cecorum expansion promoted muramyl dipeptide (MDP) release, which induced inflammatory responses by activating the NOD2-RIP2-NF-κB axis.
conclusionsCollectively, our data reveal a role of sialic acid-facilitated postantibiotic pathobiont expansion in gut dysbiosis-associated inflammation, highlighting a potential strategy for disease prevention by regulating the MDP-NOD2-RIP2 axis.
