Efficacy, safety and outcome of selective IL-23 inhibitor risankizumab in induction and maintenance of CD and ulcerative colitis: A systematic review.
Synthesis in Medicine, 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
backgroundCrohn disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases characterized by immune dysregulation. Despite biologic advancements, many patients experience treatment failure. Risankizumab (RZB), a selective interleukin-23 inhibitor, has emerged as a promising therapy for moderate-to-severe inflammatory bowel diseases. This systematic review evaluates its efficacy, safety, and therapeutic outcomes.
methodsFollowing Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search of PubMed, Embase, Scopus, and ClinicalTrials.gov was conducted to identify studies published up to 2025. Eligible studies included randomized controlled trials, clinical trials, and retrospective observational studies evaluating RZB in adult patients with CD or UC. Primary outcomes included clinical remission, endoscopic response, hospitalization rates, and adverse events.
resultsSeventeen studies involving 6602 patients (5627 with CD, 975 with UC) were analyzed. In CD, RZB demonstrated high clinical remission rates, endoscopic healing, and reduced hospitalizations, including in biologic-refractory patients. In UC, it showed significant remission rates and fewer UC-related hospitalizations. RZB was well tolerated, with mostly mild to moderate adverse events such as arthralgia, headache, and nasopharyngitis. Severe adverse events were rare.
conclusionRZB is an effective and well-tolerated treatment for moderate-to-severe CD and UC, showing strong clinical and endoscopic outcomes. It offers a viable option for biologic-refractory patients, but further research is needed to assess long-term efficacy and safety.
