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 The prognosis for surgery on acute type A aortic dissection (ATAAD) is poor because the dissected vessel is fragile and prone to bleeding. We have applied a turn-up anastomosis, in which both the Dacron graft and native aortic wall are everted for secure anastomosis. BioGlue (CryoLife, Inc., Kennesaw, GA, USA) has also been occasionally used as an adjunct. However, several potential complications associated with the use of BioGlue have already been reported. This study aimed to compare the clinical impact of BioGlue in patients undergoing ATAAD surgery using proximal turn-up anastomosis. Materials and methods Between November 2020 and March 2024, 78 cases were included for ATAAD. The proximal anastomosis was performed with a turn-up anastomosis in all cases, and BioGlue was used as an adjunct in 49 cases (BG). The cases without BioGlue (NBG: 29) and BG were compared. Results There were no differences in age, gender, preoperative shock, cardiac tamponade or malperfusion between the two groups. The replacement of ascending aorta was more common in NBG (52%, p=0.0004), while the frozen elephant trunk technique was more common in BG (59%, p=0.0004). Operation time was similar (NBG: 302 min, BG: 277 min, p=0.1451), and no significant difference in intraoperative bleeding (NBG: 1487 mL, BG: 1370 mL, p=0.6942). Both groups had no cases requiring re-anastomosis or repair under re-aortic cross-clamp. In-hospital mortality was 0% in NBG and 14% in BG (The risk difference: 0.142857 (0.044879-0.240835), p=0.0419). Re-exploration for bleeding was similar (NBG: 10%, BG: 6.1%, OR=0.565 [0.106-3.00], p=0.6651). These results were similar for the replacement of ascending aorta only. Postoperative CT scans showed no difference in complete thrombosis of the sinus of Valsalva (p=0.7019). The mean follow-up was 20 months, with one case of aortic root enlargement in BG. Conclusions Proximal turn-up anastomosis without BioGlue was shown to be non-inferior to that using BioGlue. Proximal turn-up anastomosis without BioGlue is considered an acceptable technique. The issue of potential late complications remains, and the use of BioGlue should be approached with caution, with its application appropriately limited.
