Figure 3. MACE risk according to baseline ASCVD score and waveform parameters.

The figure displays the relationship between baseline ASCVD score (in percentage) and observed cardiovascular risk (in percentage) according to 3 levels of each waveform parameter. For each parameter, the low value was defined as 2 SDs below mean; the average value as the mean; and the high value as 2 SDs above mean. AIx@75 indicates augmentation index at 75 beats per minute; ASCVD, atherosclerotic cardiovascular disease; cPP, central pulse pressure; MACE, major adverse cardiovascular event; Pb, backward pressure; Pf, forward pressure; PP, pulse pressure; and RM, reflection magnitude.
