Efficacy and safety of limb distalization after Roux-en-Y gastric bypass: a retrospective cohort study.
Article in Frontiers in surgery, 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
Introduction: Limb distalization (LD) is an option for highly selected patients with suboptimal clinical response after Roux-en-Y gastric bypass (RYGB). This study assessed the effectiveness and safety of LD in a cohort of post-RYGB patients with suboptimal results, focusing on weight loss, obesity-related diseases remission, and nutritional outcomes. Methods: Retrospective observational study of patients who underwent LD between 2011 and 2023 at our institution. Only patients with recurrent weight gain after RYGB were selected. Outcomes assessed included the percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), remission of obesity-related diseases, and morbidity. Nutritional deficiencies were also evaluated. Results: A total of 22 patients underwent LD. The interval between RYGB and LD was 116.8 months. The average BMI pre-LD was 39.0 kg/m Conclusion: LD was linked to substantial and sustained weight loss and significant remission of obesity-related metabolic diseases. Nutritional deficiencies remain a concern, particularly in patients with shorter total alimentary limb lengths, emphasizing the importance of individualized limb length and close follow-up.
