Left and right: difference of connectivity graphs for DTF and PDC, respectively for the data from Table 1 left and right; connectivity for both DTF and PDC are determined separately for their respective independent significance thresholds, PDC threshold - by authors of  in the comparison study. Then with the resulting connectivity graphs for each measure, the graph of connectivity difference is generated. Continuous arrows mark DTF confirmation of connectivity, while PDC is disconnected. Compare these two graphs to the corresponding graphs on the left side in Figure 3 and 4. In both cases, PDC connectivity graph is a substructure of the corresponding graph for DTF.
