Long-term outcomes following laparoscopic Roux-en-Y gastric bypass: weight loss and resolution of comorbidities at 15 years and beyond.

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
backgroundLaparoscopic Roux-en-Y gastric bypass (LRYGB) is the gold-standard bariatric procedure with proven efficacy in morbidly obese populations. While the short-term benefits of LRYGB have been well-documented, durable weight loss and long-term resolution of obesity-related comorbidities have been less clearly described.
methodsThis single-center study prospectively reports weight loss and comorbidity resolution in patients undergoing LRYGB between August 2001 and September 2007 with at least 15-year follow-up. Data were collected at the time of surgery; 1, 3, 6, and 12 months postoperatively; and then annually thereafter.
resultsA total of 486 patients were included in this analysis. Patients were predominantly female (88.7%), and the median age was 36.0 [IQR 29.0-45.0] years. Patients were ethnically diverse, including Black/African American (43.6%), White/Caucasian (35.0%), Hispanic (18.3%), and other backgrounds (3.1%). Mean preoperative weight and body mass index were 133.0 ± 21.9 kg and 48.4 ± 6.5 kg/m
conclusionsLRYGB provides durable weight loss for at least 15 years after surgery, with stable average relative weight loss of approximately 25% from baseline. This outcome corresponds with sustainable resolution of obesity-related comorbidities for at least 10 years after the initial operation.
