Test-Retest Reliability of Graph Metrics in Functional Brain Networks: A Resting-State fNIRS Study
Figure 5
TRT reliability of global network metrics as a function of sparsity threshold.
(A–C) The global metric reliability was derived from HbO, HbR, and HbT, respectively. Five colors correspond to five different reliability grades. The red, yellow, green, cyan, and blue colors represent excellent (0.75< ICC <1), good (0.6< ICC <0.75), fair (0.4< ICC <0.6), low (0.25< ICC <0.4), and poor (ICC<0.25) reliability of global network metrics, respectively. Cp, Lp, γ, λ, and σ denote the clustering coefficient, characteristic path length, normalized clustering coefficient, normalized characteristic path length, and small-world, respectively. Eloc and Eglob denote local efficiency and global efficiency, respectively. Q, β, and r denote modularity, hierarchy, and assortativity, respectively.
