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

backgroundExtracellular vesicles (EVs) derived from specific bacteria exert therapeutic potential on inflammatory diseases. Previous reports suggest the protective role of Odoribacter splanchnicus (O.splanchnicus) in inflammatory bowel disease (IBD). The effect of EVs derived from O.splanchnicus (Os-EVs) and the underlying mechanism on IBD were surveyed here.

methodsOs-EVs were derived with ultracentrifugation before characterization by transmission electron microscopy and nanoparticle tracking analysis. Based on IBD model mice induced by dextran sulfate sodium (DSS), the effects of Os-EVs on IBD symptoms, intestinal barrier dysfunction, and colonic apoptosis, inflammation as well as NLRP3 inflammasome activation were analyzed. NLRP3 knockout mice were exploited to judge the role of NLRP3 in Os-EVs against IBD.

resultsOs-EVs were typically shaped as a double concave disc (average diameter = 95 nm). The administration of Os-EVs attenuated DSS-induced body weight loss, colon shortening, disease activity index score, and histological injury in mice. Os-EVs could also relieve intestinal barrier dysfunction and colonic apoptosis, as evidenced by the up-regulation of zona occludens-1 and Occludin and the decrease of TUNEL-positive staining in colonic tissues of IBD mice. Os-EVs downregulated the expression of the interleukin-1β (IL-1β), tumor necrosis factor-α, and IL-6, and elevated IL-10, accompanied by blockage of the NLRP3 inflammasome activation in DSS-induced mice. Furthermore, NLRP3 knockout mice experiments revealed that the protective role of Os-EVs in IBD relies on regulating NLRP3.

conclusionOur finding indicated that Os-EVs effectively ameliorated IBD through repressing NLRP3, strongly supporting the potential of probiotic-derived EVs for alleviating IBD.
