A Real-world Meta-analysis Study of Disease Severity in European Patients Who Received Baricitinib for Atopic Dermatitis: Data from BioDay, SCRATCH and TREATgermany.

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
Clinical trials have demonstrated the effectiveness of baricitinib, an oral selective Janus kinase 1/2 inhibitor, for patients with moderate-severe atopic dermatitis, but data from real-world practice are limited. This non-interventional cohort study evaluated clinician- and patient-reported disease severity over 16 weeks using 3 national atopic dermatitis registries: BioDay (Netherlands), SCRATCH (Denmark) and TREATgermany (Germany). Absolute scores for Eczema Area and Severity Index (EASI) and itch Numerical Rating Scale (Itch-NRS) were assessed at baseline and follow-up (Week 13/16) for each registry and for the overall pooled cohort. Descriptive analyses, generalized linear mixed modelling and meta-analysis approaches were applied to complete-case and multiply-imputed datasets. In total, 264 patients (89 BioDay, 117 SCRATCH, 58 TREATgermany) were included. Results showed improvements in EASI, with 58%, 68% and 62% achieving EASI≤7 at Week 13/16 in BioDay, SCRATCH and TREATgermany, respectively. In the pooled cohort, the proportion was 62% (95% CI: 50-73%). The pooled mean EASI change was -7.8 [14.4,-1.1]. Effectiveness was generally observed in both biologic-naïve and -experienced patients. Notable heterogeneity was observed, particularly for Itch-NRS, with the proportion achieving NRS≤4 ranging from 20% (BioDay) to 71% (TREATgermany). These real-world findings support the effectiveness of baricitinib while also highlighting variability in patient outcomes.
