CCI, Charlson comorbidity index; COPD, chronic obstructive pulmonary disease; GFR, glomerular filtration rate; OAC, oral anticoagulant; SCr, serum creatinine; SD, standard deviation.
Numbers are mean ± standard deviation or n (%).
The HAS-BLED score was calculated without the use of NSAID due to a lack of information.
