Changes in Health-Related Quality of Life After Metabolic and Bariatric Surgery: A Prospective Single-Center Cohort Study.

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
Objective: Obesity impairs health-related quality-of-life (HRQoL). Substantial weight loss following metabolic and bariatric surgery improves HRQoL, but there is a need for larger long-term studies. This study aimed to examine changes in HRQoL at 2 and 5 years, comparing outcomes between Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), and to evaluate associations with pre-operative patient characteristics. Methods: HRQoL was assessed using the Short Form-36 (SF-36) questionnaire before surgery and at 2- and 5-year follow-up. Physical and Mental Component Scores (PCS and MCS) were calculated, and associations between baseline characteristics and changes in HRQoL were analyzed. Results: Of 2031 patients, 1285 completed at least one postoperative SF-36. PCS improved significantly at 2 years (mean 9.4, 95% CI 8.7-10.0) and was maintained at 5 years. MCS showed an improvement at 2 years (1.5, 95% CI 0.8-2.2) but not at 5 years. No major differences were found between RYGB and SG, except for lower MCS at 5 years in SG patients (5.2, Conclusions: Metabolic and bariatric surgery leads to sustained improvements in physical HRQoL, but the response is influenced by preoperative comorbidity.
