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
introductionThe choice of arterial cannulation site during surgery for acute type A aortic dissection varies among institutions. Common options include the femoral artery, axillary artery, apex of the heart, ascending aorta, and brachiocephalic artery. The femoral artery is the most frequently selected site at our institution. Reports on direct arterial cannulation through the brachiocephalic artery for acute aortic dissection are scarce. However, it is a potential option for safe antegrade perfusion. We report two cases where this approach was successfully employed at our institution. CASE PRESENTATION: The first case involved a 76-year-old female. Computed tomography (CT) revealed an entry site on the left side of the ascending aorta with patency of the false lumen up to the aortic arch. Surgery was performed using brachiocephalic artery cannulation and right atrial drainage to establish cardiopulmonary bypass, followed by ascending aorta replacement. The second case involved a 74-year-old male with pericardial effusion detected on CT. The entry site was identified on the left side of the ascending aorta, with patency of the false lumen up to the aortic arch, along with a 48-mm iliac artery aneurysm. Similar to the first case, axillary or apical cannulation is typically considered appropriate. Surgery was performed using brachiocephalic artery cannulation and right atrial drainage to establish cardiopulmonary bypass, followed by ascending aorta replacement. DISCUSSION: In acute aortic dissection, important conditions for the perfusion route include the ability to achieve rapid cannulation, ensuring antegrade blood flow, and avoiding vascular injury. Severe arteriosclerosis was observed in both cases, with cardiac tamponade and iliac aneurysm noted in case 2. The time from skin incision to cannulation was 15 min in Case 1 and 17 min in Case 2.
conclusionsDirect cannulation of the brachiocephalic artery during surgery for acute aortic dissection is a viable option for reducing the time required to secure arterial access. Therefore, this method may be an effective and safe alternative to antegrade perfusion.
