Figure 1: Cumulative probability of cardiovascular events by quartiles of PWV measures (A-D), derived CFVI (E), and derived CAVI (F).
cfPWV, hfPWV, and CFVI indicate central arterial stiffness (A, C, E). baPWV, haPWV, and CAVI indicate composite arterial stiffness (B, D, F). Log-rank test was used to test for any difference across the quartiles.
