Treatment patterns and outcomes in patients with steroid-dependent ulcerative colitis in Japan: a claims database study.
Article in Intestinal research, 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
BACKGROUND/
aimsGuidelines recommend that steroid treatment for ulcerative colitis (UC) is tapered or withdrawn within 3 months of initiation, and thiopurine treatment or advanced therapy is administered for steroid-dependent UC. This study aimed to clarify real-world treatment patterns and outcomes in patients with steroid-dependent UC in Japan.
methodsA retrospective analysis of JMDC (Japan Medical Data Center) claims data was conducted to identify patients with a new UC diagnosis between June 2010 and September 2019. Index dates were the UC treatment start date (initiation of any UC treatment), steroid dependence/resistance confirmation date (identification of steroid-dependent UC), and treatment intensification date (initiation of thiopurine treatment/advanced therapy).
resultsOf 5,602 patients with newly diagnosed UC, 986 (17.6%) initiated steroids within 12 months (85.4% [842/986] received 5-aminosalicylic acid at the UC treatment start date). Of these 986 patients, 429 (43.5%) were classified as steroid-dependent (steroid dependence/resistance confirmation date). Of these 429 patients, 128 (29.8%) initiated thiopurine treatment and 75 (17.5%) initiated advanced therapy (treatment intensification date); 226 (52.7%) continued with steroids only. Across these groups, 3-6% discontinued steroids within 3 months of initiation. Hospitalization due to UC in the 12 months after the treatment intensification date occurred in 24.2% (31/128) and 18.7% (14/75) of patients who initiated thiopurine and advanced therapy, respectively.
conclusionsOver half of patients with steroid-dependent UC continued steroid treatment only. Steroid discontinuation within 3 months of initiation was low, irrespective of whether thiopurines or advanced therapy were initiated. Management of patients with steroid-dependent UC in Japan requires further treatment optimization toward guideline adherence.
