Functional connectivity networks at different connectivity densities. For each scan and each individual, three essential properties of the voxel‐based functional networks were calculated at different connectivity densities, including the mean functional connectivity strength (FCS), the largest component size (LCS), and the number of isolated nodes. (A) Both the mean FCS and number of isolated voxels decreased with an increase in network density, while the LCS increased when the network density rose. (B) The Pearson correlation coefficients between any pairs of the scans across subjects on each metric. (C) Three terms of TRT reliability for each metric. For these metrics, higher correlation and reliability were found between Scan 1 and Scan 3 (long‐term I). ICC, intraclass correlation coefficient.
