Treatment patterns for advanced therapies in Canadians with moderate-to-severe inflammatory bowel disease: a retrospective cohort analysis.
Article in Journal of the Canadian Association of Gastroenterology, 2025. 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
Many patients with inflammatory bowel disease (IBD) show an inadequate response or experience a loss of response to advanced therapies. Guidelines recommend dose optimization and switching among therapies until an optimal treatment response is attained. With several advanced treatments available, we aimed to evaluate the persistence of different therapeutic sequences in IBD. The RECORDED study was a retrospective cohort study of Canadians with moderate-to-severely active ulcerative colitis (UC) or Crohn's disease (CD) who had been exposed to more than 1 advanced therapy between May 2015 and April 2021 for UC, and May 2016 and April 2021 for CD. The primary endpoint was time to permanent discontinuation of the first advanced treatment. Overall, 330 patients had CD and 344 had UC. The most common first-line treatments for CD and UC were adalimumab and infliximab, respectively. The median (95% CI) time to permanent discontinuation of first-line treatment was 12.3 (10.9, 13.6) months in patients with CD and 9.2 (8.2, 10.8) months for those with UC. The most common reason for treatment change across both diseases was lack of efficacy. First-line advanced treatments were optimized in 191 (58.1%) CD patients and 202 (59.1%) UC patients prior to permanent discontinuation. Second-line therapy was typically from a different class compared with the first-line treatment choice. The RECORDED study provides insights into the real-world sequencing and optimization patterns of advanced treatments in patients with moderate-to-severe IBD in Canada. Lack of efficacy was the most cited reason for switching to a different therapy.
