The importance of global metrics of network architecture with respect to full-scale intelligence quotient. The independent contribution of each metric was estimated as the error of the prediction of IQ of the machine learning algorithm compared with the error that results when that metric is negated. The most negative value of importance defines the limit of noise. Hence, variables with importance greater in magnitude than the most negative variable are significant.

Tables
Metric Description Clustering coefficient The fraction of the nodes of a given neighbor that are also neighbors of each other; reflects segregation/subspecialization in the network Transitivity The fraction of node triplets in the network that form a completely connected triangle; reflects segregation/functional subspecialization in the network Modularity The degree to which nodes tend to segregate into relatively independent modules; reflects segregation/subspecialization within the network Characteristic path length Minimum number of edges required to traverse the distance between 2 nodes averaged over the network; reflects the ease of information transfer across the network Global efficiency Inverse of the mean characteristic path length averaged over the network; reflects integration in the network Drug Combination No. of Patients Age Range (median) (yr) Propofol only 9 9–17 (11) Propofol + sevoflurane 6 8–16 (14) Propofol + Dex 4 4–19 (15) Propofol + sevoflurane + Dex 1 11–11 (11) None 10 9–19 (16) Note:—Dex indicates dexmedetomidine.
