Descriptive Statistics
The eligibility proportions of all patients were described. The
proportion of patients who met each inclusion criterion and conflicted
with each exclusion criterion was described.
Clinical characteristics were described and compared between the
eligible and the ineligible patients with CHADS2 scores
≥2. Categorical variables were presented as numbers and percentages.
Continuous variables were expressed as means ± standard deviation (SDs),
median value, or interquartile range. The Student’s t-test or Wilcoxon
rank-sum test was performed for continuous variables to evaluate
differences in characteristics between the two groups. The chi-square
test was used for categorical variables.
