Tofacitinib for ulcerative colitis in Brazil: a multicenter observational study on effectiveness and safety.
Observational study in BMC gastroenterology, 2025. 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
aimTo assess the real-life, long-term effectiveness and safety of tofacitinib in a large cohort of patients with refractory or difficult-to-treat ulcerative colitis (UC).
methodsThis multicenter, retrospective, observational cohort study included patients with moderately to severely active UC who received tofacitinib for at least 8 weeks. Clinical remission and response, endoscopic response and remission, biochemical response and remission, steroid-free clinical remission, primary and secondary loss of response, drug discontinuation, the need for dose optimization, the need for colectomy, and adverse events were evaluated over up to 30 months.
resultsWe included 127 patients with UC, with a mean age of 40.3 ± 14.2 years; 58.2% were male, 75.6% had pancolitis, and 79.5% had previously failed at least one biological therapy, predominantly anti-TNF agents (70.1%). Clinical remission was observed in 31.5% of patients at weeks 12-16, 46.5% at 26 ± 4 weeks, and 37.0% at 1 year. Steroid-free clinical remission was achieved in 28.6%, 44.8%, and 37.1% of patients at the same time points, respectively. Biochemical remission was achieved in 33.6% of patients at 26 ± 4 weeks and 29.3% at 1 year. Endoscopic response and endoscopic remission within 1 year were observed in 46.0% and 15.3% of patients, respectively. Ten patients (7.9%) required colectomy, and 13 patients (10.2%) required hospitalization, all of whom had been previously exposed to biologics. The colectomy rate was significantly greater in patients with serum albumin levels ≤ 3.5 g/dL (21.4% vs. 4.1%, p = 0.013).
conclusionIn this large, long-term real-world study involving patients with predominantly biologically refractory UC, tofacitinib effectively induced clinical remission and endoscopic improvement and prevented colectomy for more than 30 months, with a favorable safety profile. Notably, baseline hypoalbuminemia was associated with higher colectomy rates.
