Relationship between the MECK and ROCBP. Scatter plots of the MECK and ROCBP in the present study is shown. In this study, one patient was out of range, which means that the MECK exceeded 80 mA, as shown by the red dot. A downward rightward trend is observed. MECK, minimum evoked current of the vascular stiffness value; ROCBP, rate of change in systolic blood pressure.
