Mirrored density plot of systole (red) and diastole (blue) duration at extra- and intracranial levels in HYV (left) and HEV (right). The three lines in the density diagram represent the interquartile range and the median. Higher variability was observed in the duration of the diastolic phase. However, the systolic phase duration is less variable in both HYV and HEV at the extra- and intracranial levels
