Percentage of change in mean blood flow velocity of the middle cerebral artery during tilt before and after hemodialysis. There are no significant differences in percentage of change in mean blood flow velocity of the middle cerebral artery (gray bars) between DM and non-DM patients before hemodialysis, whereas percent reduction of mean blood flow velocity of the middle cerebral artery after hemodialysis (black bars) in patients with DM is greater (approximately threefold) than that before hemodialysis (P < 0.01) and also greater than in non-DM patients after hemodialysis (P < 0.01). Abbreviations: DM diabetes mellitus, %MCVm percentage of the change in the mean middle cerebral artery flow velocity. From Ishida et al. [9]
