Clinical, Economic, and System-Level Outcomes of Bariatric Surgery in Adults: Protocol for a Systematic Review.
Article in JMIR research protocols, 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
Background: Obesity affects approximately 880 million adults worldwide and carries substantial health, economic, and social consequences. Although bariatric surgery achieves sustained weight loss and metabolic improvement, existing systematic reviews largely predate 2020 and rarely integrate clinical, economic, and system-level perspectives within a single synthesis. Objective: This study aims to identify, critically appraise, and synthesize evidence published between 2020 and 2025 on the clinical effectiveness and economic impact of bariatric surgery in adults with obesity. A secondary, exploratory objective is to address system-level resource utilization, specifically length of stay, preoperative pathway duration, and outpatient care burden. Methods: This protocol follows the PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols) 2015 guidance and is registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD420261351022). Eligible studies will enroll adults aged 18 years or older with obesity (BMI ≥30 kg/m Results: This protocol describes a review that is currently in progress. Registration with PROSPERO was completed on April 15, 2026, and database searches were run on August 1, 2026, identifying 9400 records. Title-and-abstract screening is scheduled to begin on August 15, 2026. Data extraction and synthesis are expected to be completed by the end of 2026, with publication of the completed review anticipated in the first half of 2027. Conclusions: This protocol provides a transparent and reproducible methodology for an integrated, contemporary synthesis of the clinical, economic, and system-level outcomes of bariatric surgery in adults. The findings are intended to inform health policy, resource planning, and future research priorities.
