Note: Data are presented as rate ratios (RR) with 95% confidence intervals (CI).

^aTotal hospitalizations included first and recurrent events.

^bModels were adjusted for age, sex, body mass index, hypertension, diabetes, coronary heart disease, prior stroke/TIA, heart failure, peripheral vascular disease, renal failure, cancer, and previous falls.

^cModel was combined and adjusted for age, sex, body mass index, hypertension, diabetes, coronary heart disease, prior stroke/TIA, heart failure, peripheral vascular disease, renal failure, cancer, and previous falls.
