Prevalence of Contact Allergy to Colophonium in Dermatitis Patients: A Systematic Review and Meta-Analysis.
Synthesis 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
Colophonium is present in many consumer and industrial products, including medical devices and cosmetic products. Due to its extensive use, there is an inherent risk of developing a contact allergy to it. Previous studies have shown that the prevalence rate of contact allergy to colophonium is around 1%-2%. This meta-analysis aimed to estimate the current prevalence of colophonium contact allergy in dermatitis patients. Two authors independently searched PubMed, Embase and Web of Science for studies reporting the prevalence of contact allergy in dermatitis patients with inception through 30 June 2025. A proportion meta-analysis was conducted to estimate the pooled prevalence of colophonium contact allergy. Seventy-three studies involving 459 757 patients with dermatitis were included. The pooled prevalence of colophonium contact allergy was 3.54% (95% CI, 3.01-4.16) with an I
