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

BACKGROUND AND

aimsUlcerative colitis (UC) is characterized by disruptions of the gut microbiome and an exaggerated mucosal immune response in genetically susceptible individuals. Alterations in the composition of the intestinal metabolome associated with dysbiosis can trigger chronic inflammation. However, it remains unclear whether microbial dysbiosis is the cause or consequence of chronic mucosal inflammation. To address this gap, we aimed to investigate the potential pro-inflammatory effects of sterile fecal microbiome filtrate (FMF) using a microphysiological, immunocompetent intestine-on-chip (IoC) model.

methodsSterile FMF from UC patients with active disease (

resultsFMF from active UC patients significantly increased proinflammatory cytokines (IL-1β, IL-6, IL-8, IL-23, and MCP-1) in the vascular IoC compartment in a time-dependent manner. In contrast, FMF from non-UC or UC patients in remission had no significant impact on the proinflammatory cytokine response compared to untreated media control. Luminal-vascular permeability was increased following the FMF treatment regardless of its origin. Image-based analysis revealed increased epithelial tissue damage and reduced tissue thickness following FMF exposure, alongside decreased endothelial cell density and altered macrophage morphology, independent of UC disease activity.

conclusionsFMF from UC patients with active disease induces a robust proinflammatory cytokine response in the IoC model, suggesting that UC-associated FMF-derived factors may contribute to the initiation of inflammatory processes relevant to UC pathogenesis. These findings are derived from a simplified intestinal barrier model and require further mechanistic and physiological validation. While image analysis revealed no significant microarchitectural differences among the three FMF groups, the pipelines established standardized metrics to evaluate the impact of FMF-derived factors on intestinal tissue integrity and immune responses, providing a framework for future IoC-based research in UC.
