Long-term (11 Years) Results of Laparoscopic Gastric Bypass: Changes in Weight, Blood Levels of Sugar and Lipids, and Late Adverse Effects : Laparoscopic Gastric Bypass Results.
Article in Obesity surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeLaparoscopic Roux-en-Y Gastric Bypass (LRYGB) remains the most effective procedure to treat severe obesity with proven short- and intermediate-term benefits. The main goal is to describe the effects on weight and biochemical laboratory tests after long-term follow-up (11 years). MATERIALS AND
methodsA prospective cohort of adults with obesity treated with LRYGB between 2004 and 2010 in one center were studied. Patients with prior bariatric or upper digestive tract surgery, hiatal hernia >4 cm, alcoholism, or decompensated conditions were excluded. The study enrolled 123 patients, with a mean follow-up of 133±29 months and a 14% loss of participants.
resultsThe percentage of Total Weight Loss (%TWL) at one, five, and eleven years was 30.3±8.4%, 29.1±6.9%, and 23.4±7%, respectively. Of the patients, 61.3% (65/106) maintained a %TWL≥20 after eleven years. Recurrent Weight Gain (RWG) at five and eleven years was 2.6±11.4% and 11 ±11.5%, respectively. At the end of the follow-up, 31.1% (33/106) of patients had RWG≥15%. Hypercholesterolemia and hypertriglyceridemia improved in 85.7% (54/63) and 90.2% (7/61) of the cohort, respectively. Remission of diabetes occurred in 80% of this subgroup. Gallstones developed in 28% of patients, and bowel obstruction due to internal hernia occurred in 9.4%. Anemia due to iron deficiency appeared in 25 patients.
conclusionAfter surgery, there is a significant and durable loss of weight, with a tendency for late Recurrent Weight Gain. Furthermore, the improvement in biochemical parameters is sustained over time, but surgery's adverse effects may appear later.
