The Weekend Effect on Outcomes for Type A Aortic Dissection Surgery: A Nationwide Analysis.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesWeekend admission has been shown to influence outcomes with surgical and medical conditions. This study aimed to evaluate if surgical outcomes for acute type A aortic dissection (TAAD) vary based on weekday or weekend admission.
methodsThe Nationwide Readmissions Database was queried for hospitalizations with TAAD as a primary diagnosis that underwent surgical procedures over a 5-year period. The association between TAAD and outcomes (in-hospital mortality, days to procedure, length of stay, hospital costs, and re-admission) based on day of admission (weekday versus weekend) was examined.
resultsA total of 14 260 patients admitted to the hospital with TAAD (10 582 [74.2%] weekdays and 3678 [25.8%] weekends) were included in this analysis. Patients admitted on the weekdays tended to be older, and more commonly had undergone prior cardiac surgery. Neurologic, coronary, and renal malperfusion were more common in patients admitted on the weekend. Compared to weekday admissions with aortic dissection, weekend admissions were associated with higher in-hospital mortality (17.3% vs 15.4%, P = .027) and also associated with increased risk in a multivariate analysis. Large hospital size and teaching status also had more favourable outcomes in the multivariate analysis.
conclusionsWhile known aortic dissection risk factors significantly impact TAAD survival, patients admitted on weekends also demonstrate a higher mortality rate.
