  1. Continuous variables were present as median (Q25, Q75) or mean ± SD. Chi-square test for categorical variables and t test or wilcoxon rank sum test for continuous variables
  2. Bold letters indicate a statistically significant difference
  3. *Anticoagulation-related thromboembolism/bleeding events include cerebral hemorrhage, gastrointestinal hemorrhage, mechanical flap stuck event, cerebral infarction, myocardial infarction, because of coagulation function was abnormal
