¹Categorical variables were coded as follows: False lumen involvement (Reference: Thoracic aorta): Suprarenal abdominal aorta (Present = 1, Absent = 0), Entire aorta (Present = 1, Absent = 0). Timing of surgery (Reference: Subacute phase): Acute phase (Yes = 1, No = 0), Chronic phase (Yes = 1, No = 0).
