Diagnosis of propofol allergy (the innovative role of the basophil activation test in the identification of allergen): a case report.
Article in The Pan African medical journal, 2025. 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
Drug allergies (DA), particularly to anesthetics, are underexplored in Morocco. Traditional diagnostic methods such as skin tests and specific IgE assays are costly, risky, and often inaccessible. The basophil activation test (BAT) is emerging as a safer and more effective alternative, especially for diagnosing propofol allergy, an under-researched area. This study examines the role of the basophils activation test in diagnosing perioperative anaphylaxis to propofol. A 32-year-old woman experienced two anaphylactic reactions during fibroscopy after propofol administration. The basophil activation test (BAT) was performed one week later using diluted propofol, measuring basophil activation via CD63 and CD203c markers by flow cytometry. Results showed 0% basophil activation in the negative control, 85.7% in the positive control, and 19.05% at 1 mg/ml of propofol, with a strong correlation (0.973) between concentration and activation. The basophil activation test (BAT) offers a reliable diagnostic method, particularly in Morocco, where traditional tests are limited, providing a cost-effective solution for diverse allergens in low-resource settings.
