Sex Differences in Incidence and Risk Factors for Delayed Cerebral Ischemia Following Aneurysmal Subarachnoid Hemorrhage: A Propensity Score-Matched Analysis.
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. Cited by 2 papers.
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
backgroundAneurysmal subarachnoid hemorrhage exhibits higher prevalences in women. However, it remains unclear whether this disparity is correlated with delayed cerebral ischemia (DCI) incidence and accompanying risk factors. We aimed to clarify the sex differences in incidence and risk factors for DCI following aneurysmal subarachnoid hemorrhage.
methodsWe included consecutive patients with aneurysmal subarachnoid hemorrhage who underwent endovascular coiling in a prospective database from November 2015 to September 2023. DCI was defined using the 2010 Multidisciplinary Research Group definition. Propensity score matching and multivariate logistic regression were employed to mitigate confounders and identify risk factors, respectively. Subgroup analyses were performed to further evaluate sex differences by age groups.
resultsAmong the 905 patients included, 215 women were matched with 215 men after propensity score matching. Women exhibited a higher DCI incidence than men (64.6% versus 35.4%, odds ratio [OR], 2.17 [95% CI, 1.39-3.45];
conclusionsWomen exhibited a significantly higher tendency for DCI compared with men. Furthermore, sex-specific differences in DCI risk factors may be useful for risk stratification.
