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
introductionDumping syndrome (DS) and recurrent weight gain are among the most relevant long-term challenges following Roux-en-Y gastric bypass (RYGB). Several treatment strategies have been proposed, including pouch resizing with ring augmentation (PRRA). This study presents long-term outcomes of PRRA, with a focus on weight trajectory and the management of DS symptoms.
methodsA retrospective analysis of all PRRA procedures performed at a tertiary referral center between January 2008 and September 2023. Clinical data were obtained from electronic health records and patient questionnaires.
resultsSixty-two patients (90.3 % female, mean age at time of RYGB 40.2 ± 9.5 years, mean BMI 47.4 ± 7.9 kg/m2) underwent PRRA at a mean interval of 56.3 ± 34.6 months after RYGB. DS was the leading indication (74.2 %), followed by recurrent weight gain (24.2 %) and primary suboptimal clinical response (1.6%). Following PRRA, 62.8 % of patients (n = 45) reported long-term improvement in DS-related symptoms, and 79 % (n = 57) achieved renewed weight loss. Long-term weight stabilization was observed, with only modest recurrent weight gain (+2.1± 5.4 kg/m2from post-PRRA nadir weight) after a mean follow-up of 48.6± 40.0 months. Ring removal was required in 25.8 % of patients, predominantly due to dysphagia and regurgitation.
conclusionsPRRA is an effective revisional option for managing DS symptoms after RYGB and contributes to sustained weight stability in patients with recurrent weight gain. However, ring-related adverse effects may necessitate removal in a subset of patients.
