Primary Sclerosing Cholangitis Worsens Prognosis in Patients With Inflammatory Bowel Disease: A Propensity-Matched Cohort Study.
Article in United European gastroenterology journal, 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
backgroundFew data are available on the impact of primary sclerosing cholangitis (PSC) on inflammatory bowel disease (IBD).
objectiveWe conducted a retrospective study using TriNetX to compare the outcomes of patients with IBD and those with concomitant IBD and PSC.
methodsAll patients with a confirmed diagnosis of Crohn's disease (CD), ulcerative colitis (UC), or indeterminate colitis with or without PSC were eligible. One-to-one propensity score matching was employed to balance demographic parameters, comorbid conditions, and IBD medications between cohort 1 (IBD) and cohort 2 (IBD and concomitant PSC). The primary endpoint was a composite endpoint including the risk of mortality, hospitalization, and surgery. Risks were expressed as Hazard Ratio (HR) with a 95% confidence interval (CI).
resultsA total of 398,980 IBD patients were analyzed (cohort 1: 395,874 and cohort 2: 3106). After propensity-score-matching, 3007 patients from each group were included (mean age 48.1 ± 19.4 years, female 40%, UC 75% CD 24.8%). Approximately 1%-2% of patients were treated with advanced therapies. Cohort 2 patients had a higher risk of experiencing the composite endpoint compared to cohort 1 group (HR:1.32, 95%CI:1.23-1.42). Similarly, a higher risk of hospitalization and mortality was identified in subjects with IBD and concomitant PSC (HR:1.32, 95% CI: 1.22-1.43 and HR: 1.69, 95%CI: 1.46-1.96). Both CD and UC patients with concomitant PSC had a higher risk of achieving the composite endpoint (HR: 1.18, 95%CI: 1.02-1.37 and HR: 1.29, 95%CI: 1.18-1.40). An increased risk of mortality and hospitalization was found both in patients with CD (HR: 2.16, 95%CI:1.58-2.95, and 1.20, 95%CI:1.03-1.41) and UC (HR: 1.87, 95%CI: 1.57-2.22 and HR: 1.27, 95%CI:1.16-1.40) and concomitant PSC.
conclusionIn this administrative study of patients with IBD and PSC, concomitant PSC was associated with an increased risk of mortality and hospitalization.
