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: Fibrosis and inflammation frequently emerge soon after ileal resection for strictures in Crohn's disease (CD). Objective: This study examined the profibrotic and proinflammatory effects of conditioned media from TNF and IFN-γ (T+I)-exposed healthy and inactive CD ileal enteroids (CDiE) on subepithelial myofibroblasts (SEMF), modeling early post-ileal resection conditions in CD. Methods: Ileal enteroids from healthy subjects (HE) and inactive CD patients (CDiE) were exposed to T+I for 6 hours, followed by an 18-hour conditioning period. Conditioned media were collected and applied to human intestinal myofibroblasts (HIMF) from healthy and inactive CD ileum for 24 hours to assess proinflammatory and profibrotic gene expression. Results: T+I exposure induced epithelial damage and cell death in CDiE, while reducing proliferation and decreasing occludin and F-actin expression in both HE and CDiE. TEER (transepithelial electrical resistance) declined in CDiE but remained stable in HE. Conditioned media from T+I-exposed enteroids altered HIMF-HC (healthy control) and HIMF-CD mRNA expression, upregulating proinflammatory genes ( Conclusion: Cytokine-exposed HE- and CDiE-derived conditioned media promoted inflammation while suppressing fibrosis-associated gene expression in subepithelial myofibroblasts. Our results suggest that damaged intestinal crypts in early CD inflammation may not directly trigger certain fibrogenic markers
