Steroid with Temporary Stent Versus Steroid Alone for Preventing Stricture After Endoscopic Submucosal Dissection for Early Esophageal Cancer.
Article in Digestive diseases and sciences, 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
BACKGROUND AND
aimsPost-ESD esophageal stricture remains a major complication despite steroid prophylaxis. Temporary stent placement has been proposed as an adjunctive strategy in high-risk cases, yet its independent effect remains uncertain due to treatment selection bias. We aimed to evaluate the association between adjunctive stent placement and post-ESD stricture using multiple adjustment strategies, including inverse probability of treatment weighting (IPTW).
methodsIn this retrospective cohort study of 89 patients receiving standardized steroid prophylaxis, 31 additionally underwent temporary fully covered self-expanding metal stent placement. Multivariable logistic regression, IPTW, and doubly robust models were applied to address baseline imbalances.
resultsConventional multivariable adjustment did not demonstrate a statistically significant association between stent placement and stricture (aOR 2.07, 95% CI 0.68-6.31). However, after IPTW adjustment with adequate covariate balance (all standardized mean differences < 0.1), stent placement was associated with increased stricture risk (OR 2.39, 95% CI 1.21-4.73). This finding persisted in doubly robust analysis (OR 2.55, 95% CI 1.24-5.25). Increasing age was independently associated with stricture across models.
conclusionAnalytical approach substantially influenced effect estimates. While conventional regression did not detect a significant association, IPTW-based analyses suggested a potential increase in stricture risk with adjunctive stenting. These findings underscore the importance of addressing treatment selection bias and warrant prospective validation.
