Data are presented as mean ± SD, n=124. ∆ denotes (follow-up value – baseline value)/(follow-up time in years). Abbreviations: β₀, pressure-independent stiffness index; cPWV, carotid pulse wave velocity; cPWV_corr, pressure-corrected cPWV; D_d, diastolic diameter; D_d,corr, diameter corresponding to a pressure of 80 mm Hg; E, Young’s modulus; E_corr, pressure-corrected Young’s modulus; IMT, intima-media thickness; IMT_corr, IMT corresponding to a pressure of 80 mm Hg.

Follow-up (2.9 ± 1.0 years) values were tested against baseline values using paired t-tests: *P < 0.05, **P < 0.001.
