Distribution of the values of the functional and structural parameters of large arteries according to blood pressure (BP) classification

BP classification	n	PWV (m/s)	CA diameter (µm)	Relative distensibility of the CA (%)	CA IMT (µm)
Optimal: < 120 x 80 mm Hg	92	8.39 ± 1.62*	6541 ± 769*	5.94 ± 2.52#	586 ± 143
Normal: 120/130 x 80/85 mm Hg	42	8.83 ± 1.67	6629 ± 895	5.35±2.60	614 ± 147
Borderline: 130/140 x 85/90 mm Hg	68	9.03 ± 1.60	6968 ± 900	5.02 ± 2.46	612 ± 144

^*p < 0.05, optimal vs. borderline. CA: carotid artery; PWV: pulse wave velocity; IMT: intima-media thickness.
