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: The clinical efficacy and early outcomes of total arch replacement with frozen elephant trunk (TAR+FET) in elderly patients presenting with acute type A aortic dissection (ATAAD) remain incompletely characterized. This study aimed to comprehensively evaluate early clinical outcomes and perioperative risk profiles in elderly patients undergoing TAR+FET for ATAAD, thereby addressing gaps in the literature and providing evidence to guide surgical decision-making in this high-risk population. Methods: A multicenter retrospective analysis was conducted involving 1634 patients who underwent TAR+FET for ATAAD between 2015 and 2023 across seven cardiovascular centers. Patients were categorized into elderly (≥ 60 years, Results: Before PSM, elderly patients had higher prevalences of coronary artery disease, diabetes, and hyperlipidemia, with significantly longer intensive care unit (ICU) stay, prolonged ventilation time, and lower 30-day survival compared with non-elderly patients. After PSM, baseline covariates were well balanced; however, elderly patients continued to demonstrate worse perioperative outcomes, including longer ICU stay (68 [35-162] vs. 47 [28-113] h, Conclusion: Even after adjustment for baseline characteristics, elderly patients undergoing TAR+FET have higher risks of perioperative complications and early mortality than non-elderly patients. This unfavorable prognosis likely reflects reduced physiological reserve rather than surgical factors alone. Future strategies should emphasize individualized procedure selection and organ-protective perioperative management to improve outcomes in this population.
