Pneumococcal Vaccine Is Associated with Improved Outcomes in Inflammatory Bowel Disease: Insights from a Propensity-Matched Study in the United States.
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
introductionPatients with inflammatory bowel disease (IBD) are at higher risk of pneumonia due to the disease itself and the use of immune-modifying medications.
methodsWe conducted a retrospective analysis of TriNetX US Collaborative Network data on patients with IBD who received the 20-valent pneumococcal conjugate vaccine (PCV20). Propensity score matching was performed to adjust for differences in demographics and pneumonia-related risk factors.
resultsAfter propensity score matching, 12,796 patients were included in the analysis. The mean ages of the vaccinated and control groups were 55.2 ± 16.3 and 55.8 ± 17.1 years, respectively, with females comprising 53% of each group. The most commonly prescribed IBD therapies across both cohorts included prednisone, methylprednisolone, budesonide, and adalimumab. Compared to the control group, patients who received PCV20 experienced significantly lower risks of pneumonia, acute respiratory failure, hospital admissions, ICU admissions, and all-cause mortality. DISCUSSION: These findings align with current recommendations supporting pneumococcal vaccination in adult patients with IBD and highlight the importance of further studies to clarify the extent of vaccine-related benefit in this population.
