Suspected Alcohol-Induced Immunoglobulin A Vasculitis: A Case Series and Review of the Literature.
Article in Case reports in dermatology. 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
Introduction: Immunoglobulin A (IgA) vasculitis is a small vessel leukocytoclastic vasculitis marked by IgA-dominant immune complex deposition, typically affecting the skin, joints, gastrointestinal tract, and kidneys. While common triggers include infections and medications, alcohol is a rarely reported precipitant. Its role remains unclear but may involve mucosal immune dysregulation, impaired IgA clearance, and increased immune complex formation. Case Presentations: We report 2 adult patients with biopsy-proven IgA vasculitis presenting with recurrent lower extremity purpura. Both experienced disease flares closely following alcohol consumption and showed limited response to colchicine. Systemic involvement was absent, and laboratory evaluations were largely unremarkable. Notably, symptom resolution or marked improvement occurred with alcohol avoidance. Conclusion: These cases support a potential link between alcohol consumption and recurrent IgA vasculitis flares. Recognizing alcohol as a possible trigger may improve disease control and highlights the importance of thorough exposure histories in dermatologic assessment.
