Aortic dissection incidence, management, and outcomes: national population-based study.
Article in The British journal of surgery, 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
backgroundAortic dissection (AD) management requires early medical therapy and surgical intervention in selected patients with type A aortic dissection (TAAD) or complicated type B aortic dissection (TBAD). The aim of this study was to assess incidence trends of AD in Sweden, and sex-based differences in management and outcomes over 25 years.
methodsThe Swedish National Patient Register and Cause of Death Register were used to identify new AD between 1999 and 2023. Incidence, management, and survival outcomes were analysed relative to the general population by matching age, sex, and year.
resultsSome 15 946 individuals had AD; 12 225 were admitted to hospital alive, and, of these, 6595 (53.9%) were treated medically. Of the 5630 surgically treated individuals, 4141 (73.6%) had TAAD and 1489 (26.4%) presented with TBAD. Incidence increased significantly to 9.32 per 100 000, with an annual percentage change (APC) of 1.4% (95% c.i. 1.2% to 1.6%). Incidence was lower for women (6.25 per 100 000) than men (10.52 per 100 000), but the APC was three-fold higher in women (APC 2.3% (95% c.i. 1.9% to 2.6%)) compared with men (APC 0.8% (95% c.i. 0.5% to 1.0%)). Women presented at an older age than men (mean of 71.9 versus 67.5 years, P < 0.001), were less likely to receive surgical treatment than men (women represented 37.8% of all dissection patients, but only 33.6% of surgically treated TAAD patients and 29.3% of surgically treated TBAD patients, P < 0.001), and had worse 10-year relative survival than men (medical management: women 70.9% and men 84.1%, P = 0.0041; TAAD surgical management: women 86.6% and men 94.9%, P < 0.0001; and TBAD surgical management: women 70.9% and men 87.5% P = 0.027).
conclusionThe incidence of AD is increasing in Sweden, with persisting sex disparities in management and outcomes. These findings underscore the need for targeted interventions to improve the diagnosis, management, and prognostication of AD, especially in women.
