Rate#, incidence rate, per 10,000 person-years; Crude SHR, crude subhazard ratio.
Adjusted SHR†: multivariable analysis including age, sex, and co-morbidities (diabetes, hypertension, hyperlipidemia, COPD, heart failure, CAD, stroke, ESRD, and AF).
*p<0.05
**p<0.01.
Comorbidity‡: Patients with any one of the following co-morbidities, diabetes, hypertension, hyperlipidemia, COPD, heart failure, CAD, stroke, ESRD, and AF were classified as the co-morbidity group.
