*Indicates certain cases had missing information for the study variable. List-wise deletion was performed as necessary.
**Adjusted for age, gender, smoking status, BMI, 5m-FI, functional status, and history of bleeding disorder.
For all the dichotomous values, cases without event are considered as the reference group.
