  • Retrospective cohort study
  • registry-based
  • adjusted Cox models

Authors' conclusion

While females (vs. males) had lower adjusted mortality, females experienced a significantly greater loss in survival time than the median age- and sex-matched US population and had a greater risk of rehospitalization over 5 years following HF hospitalization.
