a
Older five-year survivors (n=1,361) diagnosed 1990–1994 with early stage I and II breast cancer at age 65 or older followed for 10 years beginning five years after index date (date of breast cancer diagnosis).
b
Comparison cohort (n=1,361) matched for health system and age, who were free of breast cancer at matched index date and followed for 10 years beginning five years after index date.
c
Hazard ratio (HR) adjusted for study site location, age, and presence of prevalent comorbidity. CI = Confidence Interval.
