Treatment Patterns and Economic Burden of Ulcerative Colitis in Japan: A Retrospective Claims Analysis.
Article in Advances in therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionThis retrospective claims analysis characterized contemporary ulcerative colitis (UC) treatment patterns and investigated the economic burden of UC in Japan.
methodsThis study used anonymized claims data in the Medical Data Vision database. Patients were included if they had a confirmed UC diagnosis and ≥ 1 claim of systemic treatment for UC (index date) between June 2018 and December 2022, in addition to continuous enrollment for ≥ 6 months before and ≥ 12 months after the index date. Patients were excluded if they were aged < 18 years at index or if they had claimed systemic UC treatment during the pre-index period, had a confirmed diagnosis of Crohn's or Behçet's disease, or had a record of colectomy during the pre-index period. Outcomes of interest were treatment patterns, healthcare resource utilization (HCRU), and UC-related costs per person per month (PPPM). Further exploratory analyses were conducted to understand whether real-world treatment patterns with conventional therapy were optimally aligned with guideline recommendations. Two definitions of suboptimal treatment with conventional therapies were identified: prolonged treatment with corticosteroids (i.e., consecutive use for > 90 days) and corticosteroid cycling (i.e., three or more ≥ 30-day corticosteroid courses over 1 year, with a ≥ 60-day gap between courses).
resultsOverall, 15,429 patients were included. The most frequently observed class of first-line treatment was 5-aminosalicylic acid monotherapy (75.0%); treatment modification was observed in 39.7% of patients. Within 1 year of follow-up, patients had a mean (SD) of 9.8 (6.8) outpatient visits, and a hospital stay was reported in 23.9% of patients. Mean total cost PPPM was ¥76,374. Of patients with ≥ 1 course of corticosteroids, 39.8% received suboptimal treatment with conventional therapies. HCRU and total costs were higher for patients with versus without suboptimal treatment with conventional therapies.
conclusionsJapanese patients with UC would benefit from treatment options that can reduce costs, HCRU, and suboptimal treatment with conventional therapies.
