Note that statistical comparison for AARO was not performed for the rTAAD with residual TBAD subgroup due to small number of subjects. Statistically significant differences are highlighted in bold.

*P < 0.05. TBAD, type B aortic dissection; TAAD, type A aortic dissection. Data for the rTAAD with AARO patient group is presented as median [min, max].
