An Asymptomatic Case of Type B Aortic Dissection Developing Type A Dissection During Interfacility Transfer: A Case Report.

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
During the transfer from a hospital to a tertiary hospital, patients with acute aortic dissection can deteriorate due to aortic rupture or extension of the dissection. Particularly when type B aortic dissection progresses to type A dissection, it can lead to serious complications. This case report that a 50-year-old man who was transferred to our institute for thoracic endovascular aortic repair for complicated acute type B aortic dissection developed retrograde type A aortic dissection and was successfully treated with total arch replacement using a frozen elephant trunk. The patient experienced retrograde type A aortic dissection during transfer for treatment of complicated type B aortic dissection while no changes in hemodynamics or symptoms were observed. After arrival at our institution, open surgical repair with total arch replacement using the frozen elephant trunk technique successfully treated the entry closure in the proximal descending aorta. The intraoperative direct echography showed no intimal tears in the ascending aorta, so total arch replacement using a frozen elephant trunk was chosen. The patient survived without any evident complications and was cured with satisfactory outcomes at a 5-year follow-up. Aortic dissection can worsen even when a patient has no symptoms or hemodynamic changes. When transferring a case of aortic dissection, caution is required regarding progression of dissection. Total arch replacement using a frozen elephant trunk for retrograde aortic dissection is effective in resecting intimal tears.
