1 · What the graph read from 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.

Abstract

backgroundTo determine if the positive outcomes from clinical trials regarding the safety and efficacy of metabolic bariatric surgery are reproducible at a national level.

methodsA longitudinal registry-based observation study with data collected from all persons undergoing metabolic bariatric surgery in Australia from 28 February 2012-31 December 2021 including data from 122,567 index patients who underwent 134,625 completed bariatric procedures. MAIN OUTCOMES AND MEASURES: Defined adverse outcomes at 90-days (unplanned readmission, intensive care admission and re-operation; death), annual change in weight (percent total body weight loss (TBWL)), diabetes treatment and need for re-operation.

results79.0% of participants were female. Mean age on the day of surgery was 44.0 years (SD 11.8; range 12.9-87.9 years) and mean BMI 41.7 kg/m2 (SD 7.6). At 5-years participants who underwent one anastomosis gastric bypass had TBWL 34.88% (SD 8.67%), roux-en-Y gastric bypass 30.73 % (SD 9.47%); sleeve gastrectomy 26.5% (SD 10.5%) and adjustable gastric bands 17.6% (SD 12.1%). At 90-days 3.6% of procedures recorded a defined adverse event. 13,904 (13.6%) primary participants reported being treated for diabetes at baseline. No medication for diabetes was required by 71.6% (follow-up 58%) at 1-year and 61% (follow-up 22%) at 5-years. 13 904 (13.6%) primary participants reported being treated for diabetes at baseline. No medication for diabetes was required by 71.6% (follow-up 58%) at 1-year and 61% (follow-up 22%) at 5-years.

conclusionsMetabolic bariatric surgery is safe and induces substantial weight loss with reduced need for diabetes medications in the real-world. CLINICALTRIALS: GOV ID: NCT03441451.
