Effectiveness and safety of mirikizumab in ulcerative colitis: real-world data from the Latium Net.
Article in BMJ open gastroenterology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo evaluate the effectiveness and safety of mirikizumab in patients with ulcerative colitis in clinical practice.
methodsWe conducted a retrospective, multicenter cohort study across five Italian inflammatory bowel disease centers. Patients initiating mirikizumab between November 2024 and May 2025 were included. The primary endpoint was steroid-free clinical remission (SFCR) at 12 weeks, defined as the absence of rectal bleeding and near-normal stool frequency without corticosteroids. Secondary outcomes included clinical response (≥30% improvement in stool frequency and rectal bleeding), biochemical response (normalisation of fecal calprotectin (FCP) and C-reactive protein (CRP)), and safety (any adverse events). Follow-up at 24 weeks was assessed when available. Subgroup analyses were performed according to prior exposure to biologics (including ustekinumab) and induction regimen.
resultsA total of 95 patients were included (mean age 49.9±16.9 years; 50.5% male); 12.6% were biologic naïve and 17 (17.9%) received extended induction. At week 12, 43.2% of patients (41/95) achieved SFCR, 61.1% (58/95) clinical response, and 32/95 (33.7%) biochemical remission. SFCR rates were similar between biologic-naïve and biologic-experienced patients (42.6% vs 43.8%, p=0.906). SFCR rates were 36.2% and 88.2% in patients receiving extended and standard induction, respectively (p=0.002). At week 24, prior ustekinumab exposure was associated with numerically lower SFCR, although this difference was not statistically significant (38.5% vs 73.7%; OR=0.22, 95% CI 0.05 to 1.01, p=0.052). Changes in biomarkers were not statistically significant at week 12 (CRP Δ-0.08 mg/dL, p=0.464; FCP Δ-249 µg/g, p=0.127). Three patients discontinued treatment due to lack of efficacy. No adverse events were observed.
conclusionMirikizumab demonstrated meaningful clinical effectiveness and a favourable safety profile in a real-world setting, including in biologic-experienced patients.
