Risk stratification for stricture formation after endoscopic submucosal dissection for esophageal dysplasia.

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
We aimed to evaluate the demographic, clinical, procedural, and histopathologic factors associated with stricture development following esophageal endoscopic submucosal dissection (ESD). We conducted a retrospective cohort study of patients undergoing ESD for esophageal lesions from 2019 to 2024 at St. Michael's Hospital, in Toronto, Canada. The primary outcome was stricture formation, defined as a symptomatic luminal narrowing at the ESD site confirmed on follow-up endoscopy, requiring intervention. Strictures requiring dilation developed in 24% of patients, 85% of which were impassable with a standard gastroscope (9.9 mm diameter). Stricture rates increased with defect circumferential involvement: <50% (7.7%), 50%-74% (11.5%), 75%-89% (23.1%), and ≥90% (57.7%). Intraprocedural local triamcinolone acetate (LTA) injection was administered in 40 of 108 patients (37%), with a mean defect circumferential size of 87.5%. Among patients receiving LTA, stricture rates varied based on defect size: for <50% circumferential defect involvement (n = 1) and 50%-74% (n = 3), no strictures developed; for 75%-90% (n = 17), 6 patients (35%) developed strictures, 5 of which were impassable; and for 90%-100% (n = 19), 11 patients (58%) developed strictures, all of which were impassable. Patients selectively discharged on prophylactic steroids demonstrated varied stricture rates depending on the steroid regimen: prednisone (61.5%), oral budesonide (26.9%), and combination therapy (7.7%). Independent predictors of stricture formation included defect circumferential involvement (OR 1.07, 95% CI 1.03-1.12, p < 0.001), length of hospitalization (OR 1.88, 95% CI 1.11-3.16, p = 0.018), and presence of deep mural injury (OR 6.28, 95% CI 1.10-35.88, p = 0.039). Stricture formation post-ESD is strongly associated with lesion and procedural characteristics, including defect circumferential involvement, deep mural injury, and length of hospitalization.
