However, in a post hoc analysis, we calculated our graph theory measures of interest from both 10 and 5 min of healthy control hdEEG data and found large and highly significant correlations between recording lengths for all measures (all r ≥ 0.800, all P < 0.001; see ‘Data Repository’), giving us confidence in the robustness of graph theory metrics in 5-min hdEEG recordings.
