Preoperative Shock in Acute Type A Aortic Dissection: Multicenter Study of Mortality and Transport Time.
Article in Annals of thoracic surgery short reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: In acute type A aortic dissection (ATAAD), early surgical intervention is critical; however, prognostic determinants in geographically stable populations remain incompletely defined. We sought to identify key predictors of in-hospital mortality in a closed regional cohort. Methods: We retrospectively analyzed patients undergoing surgery for ATAAD between January 2022 and June 2025 at 3 tertiary centers in Yamagata Prefecture, Japan. Demographics, transport time, admission to surgery interval, preoperative status, and operative variables were evaluated. Independent predictors of mortality were assessed by Cox proportional hazards modeling. Results: Of 164 patients (mean age, 66.3 ± 11.9 years; 50% male), surgical mortality was 8.5% and in-hospital mortality was 10.4%. Nonsurvivors more frequently presented with preoperative shock (41% vs 12%; Conclusions: In a geographically isolated, consistently managed cohort, preoperative shock was the dominant determinant of in-hospital mortality in ATAAD. These findings emphasize the importance of early recognition and stabilization before surgery rather than transport speed alone.
