The absolute median QC-FC correlation is another measure of the
relationship between connectivity and motion. A, The
absolute median correlation between functional connectivity and motion in a 264-node
network defined by Power et al. (2011). A lower
absolute median correlation indicates better performance. B,
The absolute median correlation between functional connectivity and motion in a second,
333-node network defined by Gordon et al. (2016).
C, Distributions of all edgewise QC-FC
correlations after each de-noising strategy, ranked according to efficacy. Results largely
recapitulated those reported in Figure 2, with
GSR-based approaches (blue frame) collectively exhibiting the best performance. Whereas
approaches that included more regressors generally yielded a narrower distribution, those
approaches that included GSR tended to shift the distribution's center toward 0.
