JAK Inhibitors in Atopic Dermatitis: Does Weight Matter? A Real-World, Nationwide Retrospective Study: IL-AD (Italian Landscape Atopic Dermatitis).
Article in Dermatology and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionJanus kinase (JAK) inhibitors are effective systemic treatments for moderate-to-severe atopic dermatitis (AD), rapidly controlling symptoms and improving quality of life. However, the impact of body mass index (BMI) on therapeutic response remains unclear.
methodsThis multicenter retrospective study analyzed data from 388 adult AD patients treated with upadacitinib, abrocitinib, or baricitinib across 25 Italian dermatology centers between May 2022 and July 2024. Patients were classified as overweight (BMI ≥ 25) or non-overweight (BMI < 25), with disease severity assessed using EASI, IGA, and Numerical Rating Scales (NRS) for pruritus and sleep disturbance over 104 weeks. The effect of different treatment dosages was also evaluated.
resultsNo significant BMI-related differences in clinical outcomes were noted at most timepoints. However, in the upadacitinib 15 mg group, non-overweight patients showed greater EASI and pruritus improvements at Week 4 (p = 0.037, p = 0.039), although these differences resolved subsequently. At Week 104, higher BMI modestly reduced EASI improvement (p = 0.045) in multivariable analysis.
conclusionsTreatment dosage consistently influenced clinical improvement regardless of BMI. These findings confirm the efficacy of JAK inhibitors across BMI categories, suggesting minimal short-term BMI influence but highlighting potential long-term considerations in overweight patients, emphasizing personalized dosing strategies and prolonged monitoring.
