The Early and Long-Term Outcomes of Total Arch Replacement Using the Frozen Elephant Trunk (FET) Technique for Chronic Aortic Aneurysms.
Article in Cureus, 2025. 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
backgroundThe favorable long-term outcomes have been reported for total arch replacement using the frozen elephant trunk technique for acute aortic dissection. However, the data on chronic degenerative aortic aneurysms treated with this technique are limited compared with those for acute aortic dissection, and the long-term outcomes are not well understood. Here, we report early and long-term outcomes of total arch replacement using the frozen elephant trunk technique in patients with chronic aortic aneurysms.
methodsWe included 37 patients with chronic degenerative aortic aneurysms who underwent total arch replacement using the frozen elephant trunk technique between January 2015 and December 2022 at the National Defense Medical College Hospital, Tokorozawa, Japan. The primary endpoints were the 30-day and five-year survival rates. The secondary endpoints were major adverse cardiac and cerebrovascular events and acute renal failure.
resultsThe 30-day mortality rate was 13.5%, and the factors influencing this rate were postoperative cerebral infarction, acute renal failure, and prolonged ventilation. The factors influencing major adverse cardiac or cerebrovascular events and acute renal failure included a history of preoperative stroke. The five-year survival rate was 61.1%.
conclusionTotal arch replacement using the frozen elephant trunk technique for degenerative aortic aneurysms at our institution yielded satisfactory early and long-term surgical outcomes.
