The statistical significance threshold was set at\n P<\/jats:italic>\n \u2009<\u20090.05.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The case group's brain functional network topology was impaired in comparison to the control group (reduced global efficiency and small\u2010worldness, increased characteristic path length). According to node and edge analyses, the case group showed topologically damaged regions in the frontal lobe and basal ganglia, as well as neuronal circuits with weaker connections. Also, there was a significant correlation between the patients' coma time and the degree (\n r<\/jats:italic>\n \u2009=\u2009\u22120.4564), efficiency (\n r<\/jats:italic>\n \u2009=\u2009\u22120.4625), and characteristic path length (\n r<\/jats:italic>\n \u2009=\u20090.4383) of the nodes in the left orbital inferior frontal gyrus. Carbon monoxide hemoglobin content (COHb) concentration and right rolandic operculum node characteristic path length (\n r<\/jats:italic>\n \u2009=\u2009\u22120.3894) were significantly correlated. The node efficiency and node degree of the right middle frontal gyrus (\n r<\/jats:italic>\n \u2009=\u20090.4447 and 0.4539) and right pallidum (\n r<\/jats:italic>\n \u2009=\u20090.4136 and 0.4501)
