Preoperative nutritional status and its association with adverse events following open abdominal aortic aneurysm repair.
Article in Frontiers in nutrition, 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
Introduction: Abdominal aortic aneurysms (AAA) are a potentially fatal vascular condition defined by an aortic diameter exceeding 3.0 cm or demonstrating a ≥50% increase in the normal diameter. This study aims to evaluate the impact of preoperative nutritional status on rupture at presentation and early postoperative complications. Methods: This retrospective, monocentric, observational study included 125 AAA patients admitted for open surgical repair (OSR). Demographic data, comorbidities, and risk factors were obtained from the hospital's electronic database. Nutritional status was quantified using albumin, total protein, Prognostic Nutritional Index (PNI), and CONUT Score. Primary outcomes were postoperative AKI and 30-day mortality. Results: The average age was 72.6 ± 7.5 years, with 83.2% of patients being male. Rupture at presentation occurred in 56.0%, AKI in 20.0%, and the 30-day mortality rate was 47.2%. Patients with poor outcomes had lower levels of albumin, total protein, and PNI, and higher CONUT Score (all Conclusion: Poor preoperative nutritional status is strongly associated with aneurysm rupture at presentation and increased 30-day mortality after OSR. However, in ruptured cases, these biomarkers may reflect acute hemorrhage and physiological stress rather than baseline nutritional status alone.
