Univariate linear regression between abdominal perimeter and cerebral hemodynamics in terms of mean flow velocity (MFV), pulsatility index (PI), and cerebrovascular reserve (CvR). β regression coefficient beta, r linear correlation coefficient. First row: all subjects. Second row: population up to 65 years. Third row: population above 65 years
