Why the study?
Does biological sex independently predict neurological outcome or survival in post-cardiac arrest patients?
Does biological sex independently predict neurological outcome or survival in post-cardiac arrest patients?
Sex-related disparities in post-cardiac arrest outcomes are explained by unfavorable arrest characteristics rather than biological sex itself.
Clinicians should not adjust post-arrest prognostication by sex; challenges unadjusted disparity analyses and reinforces need for rigorous confounder adjustment.
Highlights Women exhibited more severe neuroprognostic profiles (EEG, SSEP, NSE) after cardiac arrest. Biological sex was not an independent predictor of neurological outcome or survival after adjustment. Unfavorable arrest characteristics (particularly non-shockable rhythm) explained outcome differences. Findings underscore the need for rigorous adjustment of confounders when assessing sexrelated outcome disparities.
