Sex Differences in Stroke Frequency and Severity Following Transcatheter Aortic Valve Replacement.
Article in Journal of the American Heart Association, 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
backgroundStroke is a recognized complication following transcatheter aortic valve replacement (TAVR). Although women have historically had a higher rate of bleeding and vascular complications after TAVR, contemporary data on sex differences in post-TAVR stroke and stroke severity are lacking. Disabling strokes significantly affect quality of life and outcomes, underscoring the need to explore sex-specific variations in post-TAVR stroke risk.
methodsIn this retrospective cohort study, we included all patients who underwent TAVR in the National Inpatient Sample from 2016 to 2021. Stroke and stroke severity were ascertained using validated claims-based algorithms. Disabling strokes were defined as those resulting in death or discharge to a nonhome location. We used multivariable logistic regression to evaluate the association between sex and stroke while adjusting for covariates, including cerebral embolic protection use, and accounting for survey weights.
resultsAmong our weighted sample of 379 410 patients (43.9% female), women demonstrated higher overall in-hospital stroke incidence compared with men (2.31% versus 1.69%; adjusted odds ratio [aOR], 1.208 [95% CI, 1.082-1.350]). This difference was driven primarily by disabling strokes, which were more common in women (1.61% versus 1.01%; aOR, 1.327 [95% CI, 1.158-1.520]). Conversely, the incidence of nondisabling stroke was not statistically different between sexes (0.70% versus 0.67%;( aOR, 1.013 [95% CI, 0.844-1.215]).
conclusionsAmong patients undergoing TAVR in contemporary practice, women had a higher rate of any stroke and disabling strokes compared with men. These findings emphasize the need for tailored strategies to mitigate stroke risk and improve outcomes for female TAVR patients.
