Comprehensive Analysis of Improvements in Health-Related Quality of Life and Establishment of QALY Gains in a Government-Funded Bariatric Surgical Program with 5-Year Follow-up.
Article in Obesity surgery, 2022. 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
purposeBariatric surgery is an efficacious intervention for substantial and sustained weight reduction in individuals with morbid obesity resulting in health improvements. However, the changes to a patient's health related quality of life (HRQoL) in the medium to longer term after bariatric surgery have not been adequately characterized. Our aim was to evaluate the change to patient HRQoL 5 years following bariatric surgery in an Australian government-funded hospital system and determine the significance of relationships between change in physical and mental assessment scores and HRQoL utility scores. MATERIALS AND
methodsWe performed a longitudinal panel study of 81 adult patients who underwent primary bariatric surgery at an Australian tertiary government-funded hospital and completed multi-attribute utility (MAU), multi-attribute non-utility (MA), and disease-specific adjusted quality of life (AQoL) questionnaires before and after bariatric surgery.
resultsAt a mean (SD) 5.72 (1.07) years postbariatric surgery, participants demonstrated statistically significant improvements in mean AQoL-8D utility (0.135 (0.21); P < 0.0001), yielding a mean 3.2 (1.67) QALYs gained. Beck Depression Inventory-II scores improved (baseline mean 17.35 (9.57); 5-year mean 14.7 (11.57); P = 0.037). Short Form-36 scores improved in the domains of physical functioning and role limitations due to physical health and general health. Change in depression scores and patient satisfaction with surgery were found to be significant predictors of follow up AQoL utility scores.
conclusionsBariatric surgery improves physical and psychological quality of life measures over 5 years. The improvement of patient QALYs provide insight to the potential cost utility of publicly funded bariatric surgery in the medium term.
