Sex Differences in the Characteristics of Acute Aortic Dissection: Stanford Type A Dissection among Elderly Women in Japan.
Article in Juntendo medical journal, 2025. 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
Objectives: Acute aortic dissection (AAD) still remains a life-threatening medical emergency. However, only a few data exist on sex-related differences in patients with AAD over the recent years. Materials and Methods: The medical records of 192 consecutive patients admitted to Juntendo University Urayasu Hospital from January 2008 to December 2021 who had been diagnosed with AAD were retrospectively collected. Thereafter, sex-related differences in patient characteristics, type of dissection, maximal diameters of dissection, the onset-to-arrival time, and short-term mortality were determined. Results: A total of 164 patients were ultimately enrolled in this study. Compared to men, women were significantly older, were less obese, and had lower prevalence of metabolic syndrome. A significantly higher proportion of women than men underwent Stanford type A dissections (52% vs. 25%), except among those aged 50 years and younger. Women had significantly larger maximal aortic dissection diameters compared to men (43.3 ± 9.5 vs. 38.9 ± 7.2 mm). Women with type A dissection were older, had lower body mass index and albumin levels compared to men, and demonstrated poorer renal function than women with type B dissection. Conclusion: In the context of Japan's aging society, older, underweight women with chronic kidney disease and malnutrition may represent a high-risk population for Stanford type A aortic dissection.
