Group-level correction in addressing residual head motion impact. Two-sample t-tests were performed on each of the global topological properties between upper motion tercile (n = 32) and lower motion tercile (n = 32) of Cambridge females. The “null model” was defined by performing two-sample t-test between two “null” groups (mixing the motion terciles and equating for motion and age). The group-level correction was performed either at connection-stage (i.e., applied to the connections before topological parameter calculation), at topological parameter-stage (i.e., applied to the topological parameters after their calculation), or at both stages. For each stage, the mean iFC, mean FD, or both mean iFC + mean FD were regressed out.
