  • Observational cohort study

  • hierarchical logistic regression

Authors' conclusion

Although bystander CPR was associated with higher survival in all patients, its association with survival was weakest for Black individuals and women with out-of-hospital cardiac arrest.

Study context

Population
Nontraumatic OHCA in a large US registry, 2013 to 2022
Participants
623,342 nontraumatic OHCAs
Exposure
Bystander CPR vs no bystander CPR, by sex and race and ethnicity
Outcome
Survival to hospital discharge; differential association of bystander CPR by sex and race and ethnicity
