Nickel(II) sulphate-induced allergic contact dermatitis as experimental tool to investigate inflammatory pruritus in humans.
Article in Frontiers in allergy, 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
Allergic contact dermatitis is a leading cause of occupational skin disease, with nickel(II) sulphate representing one of the most prevalent contact allergies worldwide. Clinically, nickel-induced dermatitis is characterised by pronounced inflammation and intense pruritus. The functional role of endogenous mediators, structural neuronal changes, and molecular mediators contributing to the generation of itch in allergic contact dermatitis still needs to be investigated. We present nickel(II) sulphate-induced contact dermatitis as a mechanistic model to investigate pruritus under controlled conditions in humans. Thereby, we can combine and correlate clinical characterisation of nickel(II) sulphate contact dermatitis with psycho-physical, structural, and molecular analyses to identify inflammatory pathways, mediator profiles, and gene regulatory pathways involved in pruritus generation. By enabling the systematic characterisation of itch mechanisms at molecular, structural, and functional, levels, this approach provides a translational scope to advance our understanding of pruritogenic pathways and for developing targeted therapeutic strategies in allergic contact dermatitis.
