Outcomes after elective total aortic arch replacement: Does obesity matter?
Article in JTCVS 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
Objective: Obesity is a chronic disease linked to high mortality and morbidity after cardiac procedures, but its relationship to outcomes after total aortic arch replacement (TAR) remains unclear. We examined TAR data to determine whether obesity is associated with greater perioperative risk. Methods: Among 787 TARs performed from 1990 to 2023, we excluded patients who lacked body mass index (BMI) data, had nonelective or nonstandard repairs, or were underweight (BMI <18.5 kg/m Results: Patients with obesity had greater rates of obstructive sleep apnea, transient spinal cord deficit, and acute renal dysfunction than patients with normal weight. During repair, the use of antegrade cerebral perfusion often exceeded 30 minutes in patients with obesity. Operative mortality and adverse events did not differ among BMI or obesity groups. Greater BMI was not predictive of operative mortality, whereas chronic kidney disease (odds ratio, 2.28; Conclusions: Obesity was not associated with operative mortality or adverse events in patients who underwent TAR. Therefore, patients should not be deemed ineligible for TAR on the basis of obesity alone.
