  1. Cf-PWV carotid-femoral (Cf) pulse wave velocity, BH-PWV ascending aorta pulse wave velocity according to the Bramwell Hill Model, TTc, TTw and TTf transit times estimated using cross-correlation, wavelets and Fourier transforms, respectively. Correlation coefficients are provided along with their levels of significance, which were indicated by *** for p < 0.001, ** for p < 0.01, * for p < 0.05
