Test-Retest Reliability of Graph Metrics in Functional Brain Networks: A Resting-State fNIRS Study
Figure 11
Significant differences (paired t-test) in ICA-derived nodal metric reliability.
(A) Reliability for three nodal centrality metrics (degree, efficiency, and betweenness). (B) Reliability for three concentration signals (HbO, HbR, and HbT). Each of these three concentration signals was denoised using ICA. Note that the reliability of nodal degree and efficiency is concordant across HbO, HbR, and HbT and is also significantly (p<0.0001) higher than that of nodal betweenness. Error bars correspond to the standard deviation of the mean across the total nodes. The double asterisk indicates p<0.0001.
