Table 3.

Effects of concussion on integrated measures of mean betweenness centrality (ICB_avg), mean eigenvector centrality (ICE_avg), modularity (IMOD) and degree assortativity (IDAS), for concussed athletes at acute injury (ACU), return to play (RTP) and one year post-RTP (1YR). This includes cross-sectional differences relative to controls (CTL) and within-subject longitudinal changes between imaging sessions. Tables report bootstrap ratios (BSRs) and p-values. Significant effects at an FDR threshold of 0.05 are noted with ‘*’.
