Relationship between variability independent of the mean (VIM) and time rate (TR) of systolic blood pressure (SBP) between 24 and 72 h after recanalization. A significant negative correlation was observed between VIM and TR (Spearman’s rho = –0.162, p = 0.013), indicating a tendency to greater SBP variability in patients with an overall declining SBP trajectory
