Real-world Effectiveness and Safety of Janus Kinase Inhibitors in Alopecia Areata: A Retrospective Cohort Study of 72 Patients.
Article in Acta dermato-venereologica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 2 of them syntheses that pooled it.
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
Alopecia areata (AA) is an autoimmune hair loss disorder characterized by sudden hair shedding due to immune dysregulation involving the Janus Kinase - Signal Transducer and Activator of Transcription (JAK-STAT) pathway. JAK inhibitors (JAKi) have demonstrated efficacy in clinical trials, but data from real-world settings remain scarce. This retrospective, single-centre cohort study evaluated the real-world effectiveness and safety of JAKi (abrocitinib, baricitinib, ritlecitinib, upadacitinib, and tofacitinib) in 72 patients treated between December 2017 and February 2024. Patients had a mean age of 34 years and a mean disease duration of 8 years. At time points 3, 6, 9, 12, and 18 months substantial regrowth was observed in 18 (25%), 28 (38.9%), 25 (34.7%), 22 (30.6%), and 19 (26.4%) patients respectively. Over a median follow-up of 16 months, 61% achieved substantial regrowth at a median time of 7 months. At 3, 6, 9, and 12 months, the cumulative regrowth rates were 11.1%, 40.2%, 55.6%, and 59.7%, respectively. Among non-responders who switched medications, 75% achieved substantial regrowth. Two serious adverse events occurred (sickle cell crisis and renal failure with pre-existing dysfunction). The findings indicate that JAKi are effective and safe for AA treatment in real-world settings. Further prospective studies are necessary to optimize treatment guidelines.
