Adjustment of Surveillance Intervals for Ulcerative Colitis-Associated Neoplasia Based on Disease Duration.

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
objectivesThe risk of colitis-associated cancer increases with disease duration in ulcerative colitis (UC), yet surveillance colonoscopy protocols generally stratify risk uniformly for patients with disease lasting over 8 years. This study evaluated whether shorter surveillance intervals might enhance lesion detection rates in patients with extended disease duration.
methodsThis retrospective observational study analyzed patients diagnosed with UC-associated neoplasms between 2010 and 2023. Colonoscopies before lesion detection were retrospectively reviewed, and risk stratification was applied according to four established guidelines. The recommended surveillance intervals were recalculated based on the stratified risk, and lesion detection rates were compared across increasing risk categories for specific disease duration.
resultsA total of 39 patients were included, with a median disease duration of 21 years (14-27), and a median colonoscopy interval of 1.3 years (1.1-2.2). Lesion detection rates were 72%, 59%, 44%, and 56% for American Society for Gastrointestinal Endoscopy (ASGE), American Gastroenterological Association (AGA), European Crohn's and Colitis Organisation (ECCO), and British Society of Gastroenterology (BSG) guidelines, respectively. Adjusting risk stratification upward by one rank for disease durations of ≥ 15, ≥ 20, ≥ 25, and ≥ 30 years resulted in increased detection rates: 90%, 87%, 82%, and 72% for ASGE; 85%, 82%, 74%, and 64% for AGA; 82%, 74%, 62%, and 49% for ECCO; and 82%, 79%, 72%, and 62% for BSG, respectively. The longest period with a significant difference in detection rates was observed in patients with disease durations of 20-25 years.
conclusionsFor patients with long-standing UC, reducing surveillance intervals may improve the detection of colitis-associated neoplasia, with a practical focus on those with 20-25 years of disease duration.
