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
backgroundUlcerative colitis (UC) is a chronic inflammatory disease characterized by mucosal immune activation and epithelial barrier breakdown. The pathogenic mechanisms underlying UC remain incompletely understood, and identifying key molecular drivers of disease onset and progression may provide new therapeutic opportunities.
methodsA total of 1,446 samples were integrated to identify key genes through machine learning and SHAP analysis. Immune infiltration, cytokine activity, barrier gene expression, and clinical outcomes were analyzed. Functional and mechanistic validations were further performed in lipopolysaccharide (LPS)-stimulated HT29 cells.
resultsFBXO6, COL1A2, and NPY emerged as robust diagnostic biomarkers that stratify UC patients into molecular subgroups with distinct inflammatory states and therapeutic responses. High FBXO6 expression correlated with macrophage-driven inflammation, barrier disruption, and reduced responsiveness to biologics. Mechanistically, FBXO6 directly bound SLC3A2 and induced its degradation through K48-linked ubiquitination, thereby promoting ferroptosis and amplifying mucosal inflammation.
conclusionA previously unrecognized ubiquitin-mediated FBXO6-SLC3A2 axis was identified as a critical driver of ferroptosis and epithelial barrier disruption in UC. Targeting FBXO6 to preserve SLC3A2 stability is proposed as a potential therapeutic strategy to restore epithelial integrity and improve treatment responsiveness in patients with UC.
