Comparisons of Baseline Characteristics between Eligible and
Ineligible Patients with CHADS2 Score ≥2
Figure 1 presents the flow diagram of the study. We excluded
patients with CHADS2 <2 (n=2063, 26.4% of all
registered patients) from comparing outcomes. Table 3 presents
the baseline characteristics of the eligible and ineligible patients
with CHADS2 ≥2. Ineligible patients were more likely to
be elderly, female, and have comorbidities such as stroke, heart
failure, coronary artery disease, chronic liver disease, and kidney
disease than the eligible patients. The CHADS2 score
after excluding patients with <2 and the HAS-BLED score were
significantly higher in ineligible patients than in eligible patients.
