Article in Pediatric and developmental pathology : the official journal of the Society for Pediatric Pathology and the Paediatric Pathology Society. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06675825 (A Novel Endoscopic Attachment Cap for Benign Esophageal Stricture Dilation in Children), which is not on this map. Cited by 6 papers.

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.

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.

Abstract

backgroundEsophageal strictures (ES) in children are not well characterized pathologically. We report unique histopathologic analyses of resected acquired ES and control esophagi (CE).

methodsMuscle layer thicknesses were measured in intact well-oriented areas; inflammatory cells were counted in the most inflamed high power field (hpf). Sections were stained with relevant antibodies. Results were expressed as median, lower and upper quartiles. Wilcoxon Rank Sums non-parametric test was used to compare groups;

resultsAll ES (N = 10) showed focal replacement of lamina propria, muscularis mucosa and submucosa by actin+ fibers emanating from muscularis propria. Compared to CE (N = 8), ES displayed significantly thickened muscularis mucosa and propria, and increased mast cells (tryptase- and chymase-positive), and eosinophils in muscle layers (all

conclusionsCompared to CE, acquired ES in children show significant structural alterations, including obliterative muscularization, inflammatory cell mural infiltrates, and extracellular matrix protein deposits. Therapies targeting connective tissue expansion, mast cells, eosinophils and inflammation may be beneficial to treat ES.
