Systemic Contact Dermatitis Triggered by Benzalkonium Chloride in Laundry Detergent A Case Initially Misdiagnosed as Eczema.
Article in Clinical, cosmetic and investigational dermatology, 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
This case shows that benzalkonium chloride is an important sensitizer for contact dermatitis.The patient did not respond to conventional eczema treatment. Pathological examination and detailed history-taking revealed that benzalkonium chloride in the detergent was the causative factor. After avoiding exposure to this allergen, the condition improved, emphasizing the need to consider contact dermatitis in patients with refractory eczema.
