Distribution of the values of extracranial (green box) and intracranial (blue box) mean flow in systole (red) and diastole (blue) for HYV and HEV. Each thin grey line represents the mean flow value for each participant, and the bold line represents the total average value of the corresponding group. Systole-average flow values at extra- and intracranial levels were comparable in HYV and HEV. In contrast, diastole-average flow values at both levels were significantly higher in HYV than in HEV.
