The Relationship between Side of Onset and Cerebral Regional Homogeneity in Parkinson’s Disease: A Resting-State fMRI Study

Table 2

Brain regions with significant differences in ReHo between PD patients and control subjects.

Brain regions	Side	Peak MNI coordinates			Number of voxels	T-value	Effect size (Cohen’s ƒ^2) of LPD vs. RPD	95% Confidence interval of LPD vs. RPD
		X	Y	Z
LPD > HC
Right temporal pole	R	30	12	−36	130	5.30	0.038	−0.037, 0.137
RPD > HC
Right temporal pole	R	21	9	−42	90	4.25	0.013	−0.088, 0.101
RPD < HC
Right precentral gyrus and right middle frontal gyrus	R	36	−12	42	161	−5.49	0.06	0.016, 0.098

HC, healthy controls; LPD, Parkinson’s disease with left onset; MNI, Montreal Neurological Institute; R, right; and RPD, Parkinson’s disease with right onset.
