Network density and scale-free model fit (R2) of network based on changing PCC-cutoffs. The abscissa represented the changing PCC-cutoffs from 0.3 to 0.9. The left-blue ordinate represented network density (average node connectivity) and the right-red represented the scale-free model fit (R2) of the resulted network using a certain PCC-cutoff. It can be seen that network density decreased with the changing PCC-cutoffs, whereas the scale-free model fit (R2) increased and then decreased, reaching a maximum value of 0.87 when the PCC-cutoff is 0.7
