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
BACKGROUND AND
objectivesSome atopic dermatitis (AD) treatments have been linked to an increased risk of herpes zoster (HZ). Limited evidence suggests an independent association between atopic dermatitis and herpes zoster. The study aimed to investigate the association between atopic dermatitis and herpes zoster in the UK and to explore the role of treatments in this relationship. PATIENTS AND
methodsWe conducted a matched cohort study using routinely collected primary care data from the UK Clinical Practice Research Datalink (CPRD) Aurum database (1997-2023) and applied Cox regression models. Age, behavioral factors, several comorbid diseases and different treatment exposures were included as covariates.
resultsIndividuals with atopic dermatitis had an adjusted hazard ratio of 1.28 (95% CI: 1.27-1.29) for HZ. Adjustments for different definitions of oral corticosteroid exposure as well as other traditional immunosuppressants led to minimal reductions in the association. The risk of herpes zoster increased with AD severity (aHR for mild AD: 1.22 [95% CI: 1.20-1.23]; aHR for moderate AD: 1.28 [95% CI: 1.27-1.30]; aHR for severe AD: 2.33 [95% CI: 2.22-2.45]).
conclusionsThe risk of HZ is increased in individuals with atopic dermatitis, independent of comorbidities and the use of oral corticosteroids or immunosuppressants. This elevated baseline risk is particularly relevant because herpes zoster is also a known adverse effect of newer therapies such as Janus kinase (JAK) inhibitors. These findings may inform vaccination guidelines.
