Model 1: unadjusted association between baseline walking test category and 2-year all-cause mortality. Model 2: model 1 + the following candidate variables: age, gender, and body mass index. Model 3: model 1 + the following candidate variables: age, gender, body mass index, history of carotid artery disease, previous balloon aortic valvuloplasty, chronic liver disease, oxygen-dependent chronic obstructive pulmonary disease, Society of Thoracic Surgery risk score, and access route (transfemoral vs transapical).
