Why the study?
Does sex affect the incidence and 30-day case fatality of first stroke hospitalization across different age groups?
Population
Patients with first hospitalization for stroke in Hong Kong between 2000 and 2007
Comparison
Female sex vs Male sex
Design
Cohort
Follow-up
30 days
Key result
Women aged 35-84 years had a lower incidence of first stroke hospitalization than men, but women aged ≥85 years had a significantly higher 30-day case fatality (RR 1.14; 95% CI 1.05-1.23).

Relative Risk: 1.14 (95% CI 1.05–1.23)
Women under 85 have a lower incidence of stroke than men, but women 85 and older face a higher 30-day case fatality rate.
Wu et al. (2012) conducted an observational in Stroke. Female sex vs. Male sex was evaluated on 30-day case fatality (ages ≥85 years) (RR 1.14, 95% CI 1.05-1.23). Women aged 35-84 years had a lower incidence of first stroke hospitalization than men, but women aged ≥85 years had a significantly higher 30-day case fatality (RR 1.14; 95% CI 1.05-1.23).
