Ring Augmentation and Pouch Resizing for the Treatment of Dumping Syndrome After Roux-en-Y Gastric Bypass: A Prospective Single-Center Trial.
Trial report in Obesity surgery, 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
backgroundEarly dumping syndrome (DS) and postbariatric surgery hypoglycemia (PBH) are common side effects after Roux-en-Y gastric bypass (RYGB) and may substantially impact patients' quality of life. Established management options provide limited response in many patients. This trial tested the effect of pouch resizing and silicone ring implantation (trial intervention) in patients with dumping symptoms after RYGB.
methodsThe trial intervention was assessed in a prospective single-arm trial including 16 patients. The primary endpoint was the change in Sigstad score 12 months after surgery. Secondary endpoints included Arts dumping score, insulin secretion, and glucose uptake assessed by a mixed meal tolerance test (MMTT), weight loss, quality of life, and safety evaluated by gastroscopy and contrast swallow.
resultsThe trial intervention led to a significant improvement in Sigstad (preOP: 20.4 (95% CI 17.8-23.1); 12 months: 10.4 (6.7-14.1); P = 0.0002) and Arts dumping score (preOP: 20.3 (16.7-23.9); 12 months: 10 (6.5-13.5); P = 0.0001). Glucose uptake and insulin secretion during MMTT remained largely unchanged (AUC glucose: 21,526 (19,654-23,398) mg/dl*min vs. 12 months 22,294 (20,511-24077) mg/dl*min), P = 0.21; AUC insulin: (preOP 62897 (33,531-92,263) pmol/l*min vs. 12 months 68,974 (40,691-97257) pmol/l*min, P = 0.19). Following the trial intervention, mean weight loss was 5.1% (1.4-8.9%). No ring migration or misplacement occurred during follow-up.
conclusionsPouch resizing and silicone ring implantation led to a clinically relevant improvement in symptoms associated with DS and PBH. This was not related to an apparent impact on glycemic regulation.
