Reliability of a Vertical Reconstruction of the Abdomen Following Massive Weight Loss.
Article in Plastic and reconstructive surgery. Global open, 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: The size and shape of a patient's abdomen after massive weight loss (MWL) vary according to the extent and pattern of abdominal fat distribution. The panniculus adiposus results from a combined pull of heavy fat on the skin and the weakening of the connective tissue, creating an irreversible sagging and ptotic abdomen with several folds. Reconstruction aims to reverse the topographic anatomical changes caused by underlying pathology of central abdominal fat. This study aimed to illustrate the burden of central abdominal fat pathology after MWL and evaluate a reconstructive surgical solution termed central angiosome vertical abdominoplasty (CAVA). Methods: This retrospective cohort study included patients who underwent surgery using the CAVA method from August 2019 to August 2024. Inclusion criteria were physical burden and medical morbidity caused by abdominal skin and residual fat after MWL. Patient charts were reviewed for preoperative health status, including weight loss, comorbidities, and operative and postoperative information. Results: The study included 25 patients, aged 31-66 years, with varying degrees of weight loss. Most patients achieved weight loss through bariatric surgery. The average operative time was 150 minutes, and the resection weight ranged from 553 to 17,680 g. Complications were mostly minor, with 2 patients requiring readmission. Conclusions: The CAVA technique is designed to remove central abdominal pathology and reconstruct the abdominal wall using displaced, adjacent tissue. A focus on central abdominal resection with midline reconstruction offers a viable solution for patients burdened by central abdominal pathology after MWL.
