Efficacy of upadacitinib induction for pediatric inflammatory bowel disease.
Article in JPGN reports, 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
Objectives: Upadacitinib, a second-generation Janus kinase (JAK) inhibitor, is approved for moderate to severe Crohn's disease (CD) and ulcerative colitis (UC) in adults. Its efficacy in pediatric patients remains unclear, though early reports suggest benefits in refractory inflammatory bowel disease (IBD). However, data indicate potential relapse after dose reduction. This study evaluates upadacitinib's sustained efficacy in pediatric IBD, particularly when transitioning from induction to maintenance dosing. Methods: We conducted a case series of 16 pediatric patients (mean age 16.1 years) treated with upadacitinib for refractory IBD between 2023 and 2024. Treatment responses were analyzed in 8 patients who completed induction (45 mg daily) and transitioned to maintenance dosing (30 or 15 mg daily based on provider preference). Relapse rates and responses to dose adjustments were assessed. Results: Among the 16 patients, 8 had UC, 7 had CD, and 1 had IBD-unclassified. Seven (43.8%; 95% confidence interval [CI], 19.4%-68.1%) lost response after transitioning to maintenance, with a median time to relapse of 81.5 days. Of these, 6 (85.7%; 95% CI, 42%-99%) regained response after increasing the dose back to induction dosing. Conclusion: Our findings suggest that pediatric patients may require longer induction, higher maintenance doses, or individualized dosing due to pharmacokinetics. Given the high relapse rate in our small cohort, close monitoring and tailored treatment strategies are essential.
