Weight loss and self-perceived quality of life following laparoscopic Roux-en-Y gastric bypass: is it important?
Article in Arquivos brasileiros de cirurgia digestiva : ABCD = Brazilian archives of digestive surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWeight loss (WL) is the most commonly used datum to measure the results of metabolic and bariatric surgery. The amount of WL is generally directly and proportionally associated with the improvement in quality of life (QoL), as the greater the former, the greater the perception of well-being.
aimsTo assess the relationship between the amount of weight lost after laparoscopic Roux-en-Y gastric bypass (LRYGB) and self-perceived improvement in quality of life (QoL).
methodsThe medical records of patients who underwent LRYGB between January 2017 and December 2019 with a minimum follow-up of 3 years were analyzed. The data obtained in the subgroups made up according to percentage of total weight loss (%TWL), age, and time elapsed since surgery were compared with the self-perceived QoL by the Short Form Survey 36 (SF-36) questionnaire.
resultsA total of 95 individuals (71.6% women) with an average age of 45 years and an average postoperative (PO) follow-up of 61.1 months were enrolled. The mean pre- and postoperative weight was 114 kg and 73.4 kg, respectively, and the mean %TWL was 35.6%. According to the comparison between the data from the medical records and the self-perceived QoL assessment, D1 (physical functioning) was the best scoring domain, while D3 (pain) was the worst. There was a significant improvement of the D4 (general health) domain in patients with %TWL greater than 30% (p<0.05), D7 (role emotional), and D8 (mental health) domains in patients older than 45 years (p<0.05) and better results in D7 (role emotional) domain in patients over 5 years after surgery (p<0.05).
conclusionsGreater weight loss and age and longer time after surgery showed important self-perceived improvement in QoL after LRYGB in some assessment domains, both physical and emotional.
