Zinc Deficiency Among Patients With Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis.
Review in Cureus, 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
This systematic review and meta-analysis aimed to comprehensively evaluate the prevalence of zinc deficiency in patients with inflammatory bowel disease (IBD). A systematic literature search was conducted across PubMed/MEDLINE (Medical Literature Analysis and Retrieval System Online), Embase, Scopus, Web of Science, and Cochrane Library from inception to November 2025. Studies reporting zinc deficiency prevalence in IBD patients using validated biomarkers were included. Two independent reviewers performed study selection, data extraction, and quality assessment using the Newcastle-Ottawa Scale. Meta-analysis was performed using a random-effects model, with subgroup analyses conducted by IBD subtype. Seven studies comprising 2,403 IBD patients were included. The pooled prevalence of zinc deficiency was 35% (95% CI: 19-52%), with substantial heterogeneity (I² = 98.5%). Subgroup analysis revealed a higher prevalence in Crohn's disease patients (40%, 95% CI: 21-59%) compared to ulcerative colitis patients (33%, 95% CI: 18-51%). These findings underscore the significant burden of zinc deficiency in IBD populations and highlight the need for routine nutritional screening, particularly in Crohn's disease patients. Clinicians should consider zinc assessment as part of comprehensive IBD management, with targeted supplementation for deficient patients to potentially improve clinical outcomes and quality of life.
