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
introductionArch or proximal descending aortic aneurysms complicated by Stanford type B aortic dissection (TBAD) may require extensive open repair with an open proximal anastomosis. Although a staged modified elephant trunk strategy is a reasonable option, the need to undergo two major operations is burdensome. The frozen elephant trunk (FET) technique enables concomitant treatment of the descending aorta after arch replacement; however, persistent retrograde false-lumen perfusion may result in incomplete aneurysm exclusion and inadequate aortic remodeling. We report a single-stage approach using adjunctive balloon fracture fenestration after FET deployment. CASE PRESENTATION: A 78-year-old man was referred 63 days after TBAD onset. CT demonstrated a 60-mm enlargement of the proximal descending aorta immediately distal to the left subclavian artery, a 37-mm distal segment, and enlargement of the ascending aorta to 42 mm, making standard thoracic endovascular aortic repair unsuitable. Total arch replacement using FET was performed, followed by balloon expansion of the FET to fracture the dissection flap, after which angiography demonstrated resolution of the endoleak. At 6 months, CT revealed distal stent graft-induced new entry, along with aneurysm shrinkage, complete thrombosis, and no communication between the proximal and distal false lumens.
conclusionsBalloon fracture fenestration applied to total arch replacement with FET may interrupt retrograde false-lumen perfusion and enhance distal sealing in selected TBAD-associated arch or proximal descending aneurysms. However, careful vigilance is required to mitigate potential complications, including distal stent graft-induced new entry and spinal cord ischemia. This approach may mitigate a major limitation of staged repair, namely the risk of interval rupture while awaiting completion of the second-stage procedure.
