Main effect of group in the global network metrics

	HC	De novo PD	t value	P value (FDR‐corrected)	Cohen's d
Global clustering	0.04 (0.005)	0.03 (0.004)	t ₍₄₉₎ = 2.96	0.023	0.84
Global efficiency	0.06 (0.01)	0.05 (0.01)	t ₍₄₉₎ = 2.55	0.026	0.73
global strength	1.13 (0.15)	1.03 (0.12)	t ₍₄₉₎ = 2.51	0.026	0.72
Characteristic path length	24.49 (4.27)	26.87 (3.77)	t ₍₄₉₎ = −2.05	0.09	0.59
Density	0.14 (0.01)	0.14 (0.01)	t ₍₄₉₎ = 1.75	0.10	0.5

De novo PD patients displayed a reduced global clustering, global efficiency and global strength in comparison to healthy controls. Data are expressed as mean (SD). No main effect of group was found in the characteristic path length and density. HC, Healthy controls; de novo PD, De novo PD patients; SD, standard deviation.
