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
objectivesStroke remains a serious complication after total arch replacement (TAR). To prevent this, deep hypothermia is commonly employed during TAR. We evaluated the effectiveness of cerebral protection using deep hypothermic circulatory arrest (DHCA) during TAR with the arch-first technique, focusing particularly on patients with acute aortic dissection (AAD).
methodsThis retrospective study included 109 consecutive patients with AAD who underwent emergency TAR using the arch-first technique under DHCA, and 147 patients with non-ruptured aneurysm who underwent scheduled TAR using the same technique between October 2009 and July 2022. We reviewed these patients for major adverse events, including stroke and 30-day mortality after surgery. We also analyzed the impact of clinical variables and anatomical features on the occurrence of newly developed stroke after TAR in patients with AAD.
resultsA newly developed stroke after TAR occurred in 11 (10.1%) patients with AAD. These were attributed to embolism in eight patients, malperfusion in two patients (including one who had been comatose), and low output syndrome in one patient. A stroke occurred in 3 (2.0%) patients with aneurysm, all due to embolism (P = 0.005). The DHCA time was 37 ± 7 minutes for patients with AAD and 36 ± 6 minutes for patients with aneurysm (P = 0.122). The 30-day mortality rate was 10 (9.2%) for patients with AAD and 2 (1.4%) for patients with aneurysm (P = 0.003). In our multivariable analysis, arch vessel dissection with a patent false lumen (double-barreled dissection) was the only significant predictor of newly developed stroke after TAR for AAD (odds ratio, 33.02; P < 0.001).
conclusionsPatients with aneurysm undergoing TAR using the arch-first technique under DHCA experienced significantly better outcomes, in terms of newly developed stroke and 30-day mortality, than those with AAD. Cerebral protection with DHCA during TAR using the arch-first technique continues to be a viable option. Newly developed stroke in patients undergoing TAR for AAD appears to be associated with air emboli deriving from the residual dissection with a patent false lumen in the repaired arch vessels.
