Overview of global network results comparing the delirium group, post delirium group and control group. (A) Boxplots of overall connectivity strength and minimum spanning tree outcomes diameter, kappa, leaf and tree hierarchy for the control, delirium and post delirium group. A significant difference was found in connectivity strength between the control and the post delirium group and between the delirium and the post delirium group. A significant difference was found in diameter and leaf fraction between the delirium and the control group. (B)* A significant negative correlation was found between delirium duration and tree hierarchy. (C)* A significant negative correlation was found between delirium duration and leaf fraction. Abbreviations: M = mean, SD = standard deviation, leaf = leaf fraction, th = tree hierarchy, C = control group, D = delirium group, PD = post delirium group. *Note that data on these variables is only shown for subjects included in the delirium group.
