Prevention of Parastomal Hernia and the Prophylactic Mesh Debate: A Critical Appraisal of the Chimney Trial.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Parastomal hernia remains one of the most common long-term complications following permanent end colostomy, with significant implications for patient quality of life and healthcare resources. The recently published Chimney Trial reported a reduction in both radiological and clinically diagnosed parastomal hernia using a funnel-shaped prophylactic mesh during elective minimally invasive rectal cancer surgery. This editorial critically examines the trial's findings, strengths, limitations, and implications for clinical practice. While the results are encouraging, important questions remain regarding patient selection, mesh design, long-term safety, external validity, and clinically meaningful outcomes. Rather than closing the debate on prophylactic mesh, the Chimney Trial may redefine it by shifting attention towards the role of mesh configuration and patient-centered outcome measures.
