Laparoscopic Roux-en-Y Gastric Bypass: Evolution of Weight Loss and Metabolic Obesity-Related Complications After 15-20 Years.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundRoux-en-Y gastric bypass (RYGB) is one of the prevailing metabolic/bariatric surgical (MBS) procedures. It has been used for > 50 years, yet few long-term results (> 10 years) have been published. The aim of this study is to report 15-year results and beyond in a large patient group regarding weight loss, metabolic outcomes and long-term morbidity.
methodsOur prospective bariatric database was reviewed and analyzed retrospectively. All patients who underwent primary laparoscopic RYGB between 1999 and 2008 were included. Data was gathered during in-person visits for most patients, but also using electronic medical records, phone calls to patients and/or general practitioners.
resultsNine hundred forty-four patients underwent RYGB during the study period. All were eligible for follow-up after 15 years, and 340 were eligible after 20 years. 39 (4.1%) patients died during the first 15 postoperative years. Follow-up rates were 91.7%, 74.5% and 52.3% after 10, 15 and 20 years respectively. Weight loss peaked after 2 years when total weight loss (TWL) reached 35.1%. TWL was 28.6%, 28.4% and 26.7% after 10, 15 and 20 years. Mean body mass index decreased from 45.7 kg/m
conclusionsRYGB is an efficient MBS procedure, associated with sustained weight loss and improvement of metabolic complications; a slight worsening occurs over time, partly attributed to aging and the chronic course of obesity and related metabolic disorders.
