REAL-WORLD EXPERIENCE WITH JANUS KINASE INHIBITORS IN EXTRAINTESTINAL MANIFESTATIONS AND INFLAMMATORY BOWEL DISEASE IN COLOMBIA: A COMPARATIVE STUDY (JAKEIM-IBD STUDY).
Article in Arquivos de gastroenterologia, 2026. 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
backgroundExtraintestinal manifestations (EIMs) significantly impact patients with inflammatory bowel disease (IBD). Janus kinase inhibitors (JAKi) are emerging as a potential treatment. This study describes real-world outcomes in Colombian patients with IBD and EIMs treated with upadacitinib or tofacitinib.
methodsMulticenter study including moderate-to-severe IBD patients with EIMs. We analyzed the prevalence, resolution, and progression of EIMs with JAKi therapy.
resultsAmong 77 patients (51 UC-tofacitinib, 16 UC-upadacitinib, 10 CD-upadacitinib), 28.6% (n=22) had EIMs, primarily articular (81.25%), followed by hepatobiliary (25%), cutaneous (18.75%), and ocular (6.25%). Most tofacitinib-UC patients (90%) had prior anti-TNF therapy. During induction, 66.6% had a clinical response, and 33.3% achieved EIM remission. In maintenance, 83.3% achieved remission. Among upadacitinib-UC patients, 66.6% had prior anti-TNF, 33.3% anti-integrin, and 33.3% were biologic-naïve. Corticosteroid use was reduced in 66.7%. Induction response was 66.7%, with 33.3% achieving remission. At six months, remission was 50%. No significant difference in remission rates was observed between upadacitinib and tofacitinib (OR 1.36, 95%CI 0.43-4.33, P=0.28). In CD-upadacitinib, all patients had prior anti-TNF therapy, with 66.6% achieving remission during induction. Adverse events included alopecia, acne, and herpes zoster.
conclusionJAKi therapy is a safe and effective alternative for IBD patients with EIMs. While upadacitinib may offer superior intestinal benefits, both treatments demonstrated efficacy in managing EIMs.
