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
Background and Aims: This study surveyed Canadian inflammatory bowel disease (IBD) specialists to understand their perceptions, preferences, and practices regarding image-enhancement modalities (including dye-spray chromoendoscopy [DCE], virtual chromoendoscopy [VCE], and artificial intelligence [AI]-aided endoscopy) for colorectal neoplasia (CRN) detection in IBD, to inform future studies and recommendations. Methods: Developed collaboratively by IBD experts and methodologists, the survey assessed physicians' attitudes toward colonoscopy image-enhancement modalities for CRN surveillance in IBD, evaluating 5 domains: current practices, familiarity with advanced techniques, perceptions of AI-assisted endoscopy, barriers to adoption, and research priorities. It was distributed to IBD specialists affiliated with the Canadian IBD Research Consortium and conducted per The Strengthening the Reporting of Observational Studies in Epidemiology guidelines. Results: Of 82 specialists invited, 33 responded (40.2%). Most worked in academic centers (90%); 39.4% managed large IBD practices. VCE was the most used advanced imaging modality (84.8%), followed by DCE (33.3%), high-definition white-light endoscopy (HD-WLE) plus nontargeted biopsies (33.3%), AI-assisted colonoscopy (18.2%), and HD-WLE alone (6.1%). Although 60.6% considered DCE and VCE similarly effective, drawbacks included bowel preparation (VCE: 26.6%; DCE: 24.1%) and poor visualization with inflammation (VCE: 26.6%; DCE: 12%). AI-assisted colonoscopy was seen as promising for CRN detection; 78.8% agreed randomized controlled trials are needed, and 39.4% would adopt AI if it improved CRN detection by 5% over HD-WLE. Conclusions: This survey highlights a shift toward VCE over DCE, perceived drawbacks of chromoendoscopy, limited availability and uncertainty about AI-assisted colonoscopy, and a desire for research to demonstrate AI's utility for CRN detection in IBD.
