Transmural healing in ulcerative colitis patients improves long-term outcomes compared to endoscopic healing alone.
Article in Journal of Crohn's & colitis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 &
aimsEndoscopic healing (EH) is recognized as a long-term treatment goal for patients with ulcerative colitis (UC). We investigated whether transmural healing (TH) in UC as assessed by intestinal ultrasound (IUS) is associated with improved outcomes compared to EH alone.
methodsWe performed a retrospective study in a tertiary center on patients with left-sided or extensive UC on stable maintenance treatment who had EH [Mayo Endoscopic Subscore (MES) ≤1) and an IUS performed within 6 months of an endoscopy with no treatment alterations between IUS and endoscopy. TH was defined as bowel wall thickness (BWT) <3 mm. The primary outcome was relapse-free survival in patients with and without TH.
resultsA total of 61 patients (MES 0: 44.3%; MES 1: 55.7%) with a median follow-up of 20 months were included. On IUS, 72% of patients had TH. Twenty-three patients had a relapse (first-year relapse risk: TH: 7.5% vs no TH: 29.4%, P = .004; MES 0: 3.7% vs MES 1: 20.8%, P = .059). In multivariate Cox regression, female gender [hazard ratio (HR), 2.63; 95% CI 1.05-6.58; P = .039], two or more previous advance therapies (HR, 4.06; 95% CI 1.08-15.28; P = 0.038), and non-TH (HR, 3.99; 95% CI 1.31-12.20; P = .015) were associated with a relapse whereas EH level (MES 0 vs MES 1) was not an associated factor (HR, 1.06; 95% CI 0.32-3.55; P = .924).
conclusionsIn UC patients TH is associated with lower relapse risk compared to EH alone. These findings imply that IUS is a non-invasive, low-cost alternative to endoscopy for stratifying UC patients for risk of relapse.
