DMN network attribute parameters in three different alertness states

Index	Awake state	Light sedation state	Deep sedation state
Mean degree	4.58±0.71	3.66±1.01▲	2.97±0.78*
Shortest path length	2.74±0.41	3.46±0.83▲	4.31±0.91*
Global efficiency	0.45±0.05	0.37±0.08▲	0.31±0.06*
Local efficiency	0.39±0.06	0.30±0.09▲	0.24±0.07*
Clustering coefficient	0.38±0.07	0.29±0.09▲	0.23±0.07*

Notes: Results are shown as mean ± standard deviation, n=12. P<0.01 between the three groups for all variables, according to analysis of variance.

^▲P<0.01 between light sedation and awake states;

^*P<0.01 between deep sedation and awake states. There was no significant difference between light and deep sedation states.

Abbreviation: DMN, default mode network.
