TRT reliability of nodal centrality metrics as a function of sparsity threshold.

<p>(A–C) The nodal metric reliability was derived from HbO, HbR, and HbT, respectively. The five colors correspond to five different reliability grades: red, yellow, green, cyan, and blue represent excellent (0.75< <i>ICC</i> <1), good (0.6< <i>ICC</i> <0.75), fair (0.4< <i>ICC</i> <0.6), low (0.25< <i>ICC</i> <0.4), and poor (<i>ICC</i><0.25) reliability of the nodal centrality metrics, respectively.
