Contact Sensitisation Trends in Slovenian Children and Adolescents: A Retrospective Single-Centre Study.
Article in Contact dermatitis, 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
backgroundExisting data on contact sensitisation prevalence among children and adolescents is limited, especially regarding comparisons of specific allergens over extended timeframes. The objective of this study was to identify the most common allergens and to evaluate shifts in contact sensitisation trends.
methodsWe retrospectively evaluated patch test data of 1052 children and adolescents referred to a single tertiary medical centre. The analysis covered three periods: 2000-2004, 2010-2014, and 2020-2024. All patients were tested with the time-recommended baseline series of allergens.
resultsA significant decrease was reported for nickel prevalence, dropping from 12.6% to 4.0%. Although tested only in the latest period, textile dye mix (4.7%) and methylisothiazolinone (3.2%) emerged as important allergens. Children with atopic dermatitis (AD) showed a higher prevalence of contact sensitisation (27.7% vs. 22.7%). In contrast, among adolescents, rates were lower in those with AD (20.0% vs. 30.7%).
conclusionsOur findings demonstrate a marked decline in nickel sensitisation, while dyes and preservatives are gaining importance. The clinical relevance of specific allergens is evolving in response to regulations and market trends. Continuous surveillance of contact sensitisation is also essential in the pediatric population to ensure that patch testing strategies and preventive measures remain current, targeted and effective.
