Further study details as provided by Yonsei University:

Primary Outcome Measures:
  • Investigation of arterial hemodynamics [ Designated as safety issue: No ]
    Investigation of arterial hemodynamics included peak systolic velocity [PS], end diastolic velocity [ED], mean velocity [MV], time-averaged maximum velocity [TAmax], time-averaged mean velocity [TAmean], pulsatility index [PI], volume flow [VF], and dorsalis pedis artery diameter [D].
