Long-Term Outcomes and Rebleeding Risk Factors in Suspected Small Bowel Bleeding: A Study Based on the Modified Saurin Classification.
Observational study in Digestive diseases and sciences, 2026. 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
backgroundSmall-bowel endoscopy is essential for diagnosing and managing suspected small bowel bleeding (SSBB); however, rebleeding after treatment remains clinically challenging. Although several rebleeding prediction models have been proposed, few are based on endoscopic findings, and data on long-term outcomes are limited.
aimsThis study aimed to evaluate rebleeding risk factors and long-term outcomes using the modified Saurin classification (modified SC), which is compatible with balloon-assisted endoscopy (BAE).
methodsWe retrospectively evaluated 278 consecutive patients with OGIB who underwent capsule endoscopy (CE) or BAE between October 2008 and December 2023. The lesions were categorized using modified SC as P0 (n = 58), P1 (n = 109), P2 (n = 71), or no findings (n = 40). Treatment was classified as endoscopic or definitive (surgical or interventional radiology).
resultsOf the 278 patients (mean age 67.7 years; 150 males), 158 had occult OGIB and 120 had overt OGIB. Treatment was administered to 73 patients (46 endoscopic and 27 definitive cases). Over a mean follow-up of 2.2 years, 32 patients (11.5%) experienced rebleeding. Multivariate analysis identified modified SC P1 lesions (odds ratios [ORs], 2.33; p = 0.03), antiplatelet drugs use (ORs 3.02, p = 0.04) and treatment interventions (ORs, 2.28; p = 0.02) as independent predictors. The 3-year rebleeding rate was higher in P1 (27.2%) than in P0 (9.5%) and P2 (13.8%). Rebleeding was more frequent in the endoscopic group (39.9%) than in the definitive group (10.5%; p = 0.04).
conclusionModified SC P1 lesions were significantly associated with rebleeding. Proactive treatment strategies and long-term follow-up are crucial for effective management of SSBB.
