A Population-Based Study of Bariatric Surgery Trends in Australia: Variations Reflect Continuing Inequities in Access to Surgery.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundObesity is increasingly prevalent and associated with higher morbidity and mortality. Bariatric surgery, particularly sleeve gastrectomy, provides durable weight loss and improves obesity-related conditions like type 2 diabetes and cardiovascular disease. Despite its benefits, significant concerns regarding inequities in access to bariatric surgery persist. This study aims to evaluate recent trends in bariatric surgery rates and to investigate patterns of access to bariatric surgery.
methodsA population-based study of age-adjusted bariatric procedure rates in adults in NSW, Australia, was conducted over the financial years 2013/14 to 2021/22. Trends in age-adjusted procedure rates were assessed by demographics and healthcare settings.
resultsIn 2021/22, 179.6 bariatric procedures per 100,000 population were performed, an 89.7% increase since 2013/14 (p < 0.001). Laparoscopic sleeve gastrectomy, the most common procedure, increased by 94.1% to 112.6/100,000/year (p < 0.001). Females had 3.6 times higher rates than males (232.3/100,000/year vs 64.9/100,000/year). The greatest increases occurred in younger patients (125.9% in the 18-24 age group; 142.4% in the 25-34 age group, p < 0.001). Private hospital rates were 15.6 times higher than public (132.2/100,000/year vs 8.5/100,000/year) and rose 92.3% (p < 0.001), whilst public hospital rates declined by 17.9% (p = NS). Patients from regional areas had the highest rates (175.7/100,000/year) and largest increase (169.8%; 89.4/100,000/year to 241.8/100,000/year, p < 0.001).
conclusionsBariatric surgery rates continue to increase, particularly among females, despite similar obesity prevalence between sexes. Most surgery is conducted in the private sector, suggesting differential access based on financial circumstances. Rates are highest in younger people, although obesity-related comorbidities increase with age. Regional patients undergo surgery at higher rates than rural patients despite greater obesity prevalence with increasing rurality. Efforts to address these disparities are essential to improve equitable access to obesity treatments.
