We used the Kaplan-Meier product limit method to estimate rates and Cox proportional hazards regression analysis with bootstrap validation to model significant independent predictors of and temporal trends in survival and recurrent stroke among 1,111 residents of Rochester,MN,who had a first cerebral infarction from 1975 through 1989.Neither the year nor the quinquennium of the first cerebral infarction was a significant determinant of survival or recurrence.The temporal trend toward improving survival after the first cerebral infarction documented in Rochester,MN,in the decades before 1975 has ended. |
