Age, gender, and within-scanner movement parameters of the study sample.

Group	n	Age: mean (±sd)	P (t-test)	Gender: females (%)	P (χ2- test)	RMS: mean (±sd)	P (t-test)	DVARS: mean (±sd)	P (t-test)	FD: mean (±sd)	P (t-test)
Patients	39	62.6 (±9.1)	0.119	12 (31%)	0.115	0.36 (±0.16)	0.226	1.93 (±0.51)	0.140	0.51 (±0.22)	0.115
Controls	44	59.4 (±9.6)		21(47%)		0.31 (±0.24)		1.77 (±0.51)		0.41 (±0.31)

Movement parameters refer to patient's scans under their regular dopaminergic medication (medical ON). RMS, root mean squared movement; DVARS, root mean squared signal change across time-series; FD, framewise displacement.
