Impact of body mass index on outcomes in acute type A aortic dissection.
Article in Frontiers in cardiovascular medicine, 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: Elevated body mass index (BMI) is associated with adverse outcomes after cardiac surgery, but its impact in acute type A aortic dissection (ATAAD) surgery is unclear. We assessed the relationship between BMI and outcomes after ATAAD repair. Methods: An institutional retrospective cohort review was undertaken of all consecutive patients who underwent repair of ATAAD between July 2014 and December 2022 ( Results: Thirty-day operative mortality for the entire cohort was 12.8% ( Conclusion: The obesity paradox in cardiac surgery remains incompletely understood. In this cohort, BMI was not associated with increased 30-day mortality following ATAAD repair, with class I obesity demonstrating lower adjusted mortality. These findings support the continued practice of expeditious surgical intervention for ATAAD regardless of BMI.
