Sex-Specific Association Between Socioeconomic Status and Stroke Mortality.
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. 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
backgroundSocioeconomic status and sex each independently influence stroke outcomes. However, their intersectional effects remain unclear. Accordingly, we sought to assess whether the association between socioeconomic status and outcomes in stroke varied by sex.
methodsWe conducted a retrospective cohort study using the National Inpatient Sample (2016-2021). Patients with a primary diagnosis of acute ischemic stroke, intracerebral hemorrhage, or subarachnoid hemorrhage were analyzed in separate cohorts. The primary exposure was socioeconomic status (ZIP code income quartile). Multivariable logistic regression was used to assess the effect of socioeconomic status on stroke outcomes. Significant first-order sex-income interactions were observed across all stroke subtypes; accordingly, we built sex-stratified models.
resultsA total of 2 836 254 acute ischemic stroke, 406 550 intracerebral hemorrhage, and 134 510 subarachnoid hemorrhage admissions were included. In male patients, patients from the lowest quartile of ZIP code income quartile had significantly increased odds of inpatient mortality across acute ischemic stroke (odds ratio [OR], 1.11 [95% CI, 1.03-1.21],
conclusionsSocioeconomic disadvantage was associated with worse outcomes in stroke among male but not female patients. These findings highlight a sex-specific disparity in stroke outcomes and underscore the need for public health initiatives targeting male patients experiencing socioeconomic disadvantage.
