Risk factors of inflammatory bowel disease complicating anemia: A systematic review and meta-analysis.
Synthesis in Medicine, 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
backgroundInflammatory bowel disease (IBD) frequently complicates with anemia, which worsens disease prognosis and quality of life. However, the risk factors for IBD complicating anemia remain unclear. This study aims to systematically evaluate the risk factors of anemia in patients with IBD, and provide evidence for clinical practice.
methodsWe systematically searched PubMed, Web of Science, Embase, Cochrane Library, CNKI, Wanfang Data, Cqvip, and SinoMed databases up to December 1, 2024. Literature screening, data extraction, and quality assessment were independently performed by 2 reviewers. Meta-analysis was conducted using Review Manager (RevMan) version 5.3.
resultsFourteen studies, involving 111,940 patients, were included. Six significant risk factors were identified: advanced age (odds ratio [OR] = 1.07), smoking history (OR = 1.88), active disease (OR = 2.11), elevated C-reactive protein levels (ulcerative colitis: OR = 2.20; Crohn disease: OR = 2.06), decreased albumin levels (ulcerative colitis: OR = 0.78; Crohn disease: OR = 0.88), and penetrating disease behavior (B3) (OR = 6.08).
conclusionMultiple factors are associated with an increased risk of anemia in patients with inflammatory bowel disease. The early identification of these factors may facilitate timely risk stratification, closer monitoring, and targeted interventions.
