Management and Genetics of Alopecia Areata within the USA: A Cross-Sectional Study of All of Us.
Article in Skin appendage disorders, 2025. 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
Introduction: Alopecia areata (AA) is a difficult to treat and appearance altering disorder affecting up to 2% of people during their lifetime. Understanding current management trends will help in improving patient outcomes. The aim of this study was to determine the impact of comorbid disorders and demographic factors on the management of AA and determine the influence of previously discovered genetic factors in different ethnic groups. Methods: We used the All of Us controlled dataset (version 7) and examined electronic health record and genomic data from 206,173 participants in a retrospective cross-sectional study conducted in outpatients in the USA. Results: We found that AA patients with comorbid atopic dermatitis, psoriasis, and vitiligo were more likely to have been prescribed topical corticosteroids. Patients that were not of European/Caucasian ancestry were less likely to be prescribed any type of corticosteroid. We also found that specific genetic variations (single nucleotide polymorphisms) that increased or decreased risk in European/Caucasian participants did not necessarily have the same effect in other ethnicities (Hispanics and blacks). Conclusion: This work has helped uncover the state of AA care within the USA and has identified access to healthcare inequities in different ethnic populations.
