Purplish Terminal Ileum: Adult IgA Vasculitis Mimicking Crohn's Disease.
Article in ACG case reports journal, 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
Immunoglobulin A (IgA) vasculitis is a systemic small-vessel vasculitis with frequent gastrointestinal involvement; however, isolated terminal ileitis mimicking Crohn's disease is rare in adults. We report a case of a previously healthy adult patient who presented with acute abdominal pain and bloody diarrhea, with imaging and endoscopic findings suggestive of Crohn's disease. Colonoscopy revealed isolated terminal ileitis with a distinctive purplish cyanotic appearance. The development of palpable purpura and biopsies demonstrating IgA deposition in the skin and ileal tissue confirmed the diagnosis of IgA vasculitis. Recognition of characteristic endoscopic vascular features is critical to avoid misdiagnosis and inappropriate biological therapy.
