Inflammatory Bowel Disease Incidence following COVID-19: A Systematic Review and Meta-Analysis.
Review in GE Portuguese journal of gastroenterology. 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: A surge of cases of autoimmune and inflammatory diseases, such as inflammatory bowel disease (IBD), have been reported after coronavirus disease 2019 (COVID-19). Objective: The objective of this study was to assess whether COVID-19 has a role in IBD risk. Methods: We searched MEDLINE (PubMed), Cochrane Library and OpenGrey databases up to October 30, 2025, for studies evaluating the incidence of IBD following COVID-19 infection (PROSPERO ID: CRD42024534916). Results: After a full-text review of 84 manuscripts, a total of 8 studies were used in the qualitative analysis. The studies were conducted between 2023 and 2024 and included in total 28,659,801 people, 8,560,826 of which were previously infected with COVID-19 and 20,098,975 that served as healthy controls. The results from the pooled synthesis of 6 studies indicate a 39% higher incidence of IBD in people that were previously infected with COVID-19 (risk ratio [RR] 1.39, 95% CI: [1.12-1.74], Conclusions: The findings of the present meta-analysis suggest an increased risk of IBD after COVID-19 infection. Although this is more evident regarding ulcerative colitis, we believe that the available outcomes arising from future studies will clarify the real incidence of Crohn's disease following COVID-19 infection.
