Data are mean±SD. T_car-fem=time delay of carotid and femoral arterial pressure waveform, T_ref=time of return of reflected wave evaluated with the cross-correlation method, T_{ref_inf}=time of return of reflected wave evaluated with the second-order derivative method, PWV=pulse wave velocity, AIx=augmentation index, L_aorta=the aortic length, L_arch-ref=the length from the top of the aortic arch to the major reflection site estimated with T_ref, L_{arch-ref_inf}= the length from the top of the aortic arch to the major reflection site estimated with T_{ref_inf}.
