Histopathologic Concerns and Diagnostic Challenges in Hirschsprung's Disease: An Eastern European Single-Center Observational Study.
Article in Life (Basel, Switzerland), 2025. 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
backgroundWe proposed a comprehensive clinicopathological study involving the characterization of the study cohort and a comparative analysis of biopsies and surgical specimens from patients with Hirschsprung's disease. The study was complemented by the diagnostic value of calretinin, CD56, and S-100 immunohistochemistry.
methodsDescriptive statistical analysis of diagnostic variables in the group of biopsy specimens (n = 32) and bowel resection specimens (n = 16) was performed. The pattern of calretinin and CD56 expression in Meissner's plexus elements was analyzed and the maximum thicknesses of the nerve fibers were measured using morphometry with S100-immunostained sections.
conclusionsCoupled calretinin-CD56 immunohistochemistry is useful in diagnosing ganglion cell paucity biopsies or specimens with incomplete submucosa. In cases where there are no ganglion cells but there are calretinin-positive nerve fibrils in the lamina propria without nerve trunk (NT) hypertrophy, re-biopsy is the best solution. The significant differences in NT size between biopsies and surgical specimens highlight the importance of assessing NT diameter in all tissue samples examined.
