South African Flag Sign in Contrast-Induced Kounis Syndrome: When the Flag Misleads.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
case summaryA 45-year-old woman with myasthenia gravis developed acute chest pain minutes after iodinated contrast administration. Electrocardiography showed high lateral ST-segment elevation. Emergent coronary angiography revealed no obstructive disease, with rapid resolution of ST-segment changes. Elevated troponin and regional wall motion abnormality were noted. The temporal association supported a diagnosis of type I Kounis syndrome. TAKE-HOME MESSAGES: Contrast-induced hypersensitivity can mimic ST-segment elevation myocardial infarction, with characteristic electrocardiographic patterns. Urgent angiography remains essential when occlusive myocardial infarction cannot be excluded.
