Sex and Racial Differences in Left Atrial Appendage Morphology.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundBlack and female patients with atrial fibrillation have more strokes. Certain left atrial appendage (LAA) morphologies impose a higher stroke risk. Whether anatomic differences in LAA morphology are associated with race or sex remains unexplored.
methodsWe identified consecutive patients with computed tomography for LAA morphology and categorized each patient by self-reported race (Black versus non-Black) and sex. Each LAA morphology was assigned a score based on published relative LAA thrombus risk (lowest to highest: "chicken wing," "windsock" and "cactus," "cauliflower"). Scores and prevalence were compared across races and sexes using a Wilcoxon rank-sum test and Fisher's exact test, respectively. Logistic regression was performed to find the association of race (adjusting for sex) and sex with higher risk LAA morphologies.
resultsAmong 211 patients (27% Black, n=58; 47% female, n=100), there was no difference in the projected hypothetical stroke risk across race or sex (median for Black versus non-Black patients: 1 [interquartile range, 1-4] versus 1 [interquartile range, 1-1],
conclusionsThe highest risk LAA morphology, cauliflower, demonstrated greater odds of being present in Black patients versus non-Black patients. The difference in women versus men did not reach statistical significance. Although the study was underpowered to make the findings declarative, these results are provocative regarding the differential stroke risk across races and sexes.
