Main effect of group in the eigenvector centrality

Regions	HC	De novo PD	t value	P value (uncorrected)	Cohen's d
Right olfactory	0.005 (0.003)	0.004 (0.002)	t (49) = 2.29	0.025	0.65

The Olfactory area was found to be less central in the de novo PD patients relative to HCs. Data are expressed as mean (SD). T‐values were obtained from 2‐sample t‐test. Subscripted numbers in parentheses represent the degree of freedom. HC, healthy controls; De novo PD, de novo PD patients; SD, standard deviation.
