Stroke risk and mid-term survival by proximal extent of endovascular aortic repair.

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
backgroundRecent advancements in endovascular aortic repair (EVAR) have expanded treatment to increasingly proximal aortic segments, including the thoracic and thoracoabdominal aorta as well as the arch. Coherent real-world data on stroke risk after EVAR, stratified by the proximal landing zone, and the impact of perioperative stroke on mid-term survival are scarce.
methodsA population-based multiregistry retrospective analysis was performed on prospectively collected data for all EVARs performed in Sweden between 15 May 2018 and 15 May 2023. Data were collected from the Swedish Vascular Registry (Swedvasc) and cross-referenced with the Swedish Patient Registry, the Swedish Cause of Death Registry, and the Swedish Stroke Registry. The effect of perioperative stroke on mid-term survival was analysed and the relationship between the incidence of stroke and the proximal landing zone was analysed.
resultsSome 4842 EVARs were performed. Perioperative stroke occurred in 1.6% (79 of 4842). Stroke risk was associated with the proximal landing zone, with a stroke rate of 22% in zone 0. In multivariable analysis, the OR for stroke in zone 0 was 41.58 (95% c.i. 18.46 to 93.70); P < 0.001. The 30-day mortality rate was 24% (19 of 79) and 3.5% (169 of 4763) for patients with and without perioperative stroke respectively. This difference persisted over time, with a 4-year survival probability of 48.6% and 72.5% for patients with and without stroke respectively (HR 2.17 (95% c.i. 1.26 to 3.72); P < 0.001).
conclusionStroke is strongly associated with the proximal landing zone, being more likely when landing proximal to the supra-aortic vessels. Perioperative stroke impacts patient survival and should be taken into consideration during patient selection, and efforts should be made to reduce the risk of stroke during proximal repair.
