Table 6. Head motion parameters.

Quantity	CTR	PD	p-value	Significant
Max motion [mm]	0.81 (0.61)	1.08 (0.56)	0.06	2 (1 negative)
RMS motion [mm]	0.60 (0.55)	0.82 (0.60)	0.09	0 (0 negative)
Max FD [mm]	0.88 (0.59)	1.13 (0.61)	0.07	1 (0 negative)
RMS FD [mm]	0.28 (0.15)	0.28 (0.15)	0.47	1 (0 negative)

Notes: Maximal motion, root mean square (RMS) motion, maximal framewise displacement (FD) and root-mean square framewise displacement (RMS FD) for controls (CTR) and patients (PD). Quoted are the mean values and their standard deviations. We performed a two-sample t-test to test for between-group effects. The p-values are quoted. We also listed the number of edges which significantly correlated to each of the motion parameters.
