Postoperative upward and downward blood pressure deviation. Each column represents a median (with interquartile range) for upward and downward blood pressure deviation values for systolic blood pressure (SBP) (left) and mean arterial pressure (MAP) (right) separately for the group of patients without POD (Non-POD) and the patients with POD (POD); upward deviation values = maximum value minus reference value (negative values are set to 0), downward deviation values = reference value minus minimum value (negative values are set to 0); p-values corresponding to testing for differences with Wilcoxon signed rank test; significant p-values are bold
