Acute Sulfite-Induced Hypersensitivity Reaction Following Balsamic Vinegar Consumption: A Case Report.
Article 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
Sulfite sensitivity is an underrecognized cause of acute adverse reactions to preserved foods and beverages. Although sulfites are widely used as antimicrobial and antioxidant agents, hypersensitivity reactions may occur even in individuals without a prior allergy history. We report the case of a 68-year-old otherwise healthy male who developed an acute systemic reaction shortly after ingesting balsamic vinegar containing sulfites. The episode was characterized by severe epigastric burning pain, flushing, diaphoresis, and intense autonomic discomfort associated with a subjective sensation of heat requiring removal of clothing for relief. Symptoms resolved spontaneously within approximately one hour without medical intervention. The patient had long tolerated balsamic vinegar of Modena from another manufacturer without labeled sulfites and without adverse effects. This presentation suggests a sulfite-induced hypersensitivity reaction with predominant gastrointestinal and autonomic manifestations rather than classic respiratory findings typically associated with immunoglobulin E (IgE)-mediated reactions. Recognition of such reactions is important to prevent misdiagnosis and unnecessary diagnostic testing.
