Table 2. Voxel-wise topographical correlation (r) of the PD, MSA and PSP-related brain networks.

	PDRP	PSPRP	MSARP
PDRP	.	0.1031 (p = 0.459)	−0.2806 (p = 0.075)
PSPRP	0.1031 (p = 0.459)	.	0.3549 (p = 0.021)
MSARP	−0.2806 (p = 0.075)	0.3549 (p = 0.021)	.

^*p<0.05 after Bonferroni correction for multiple comparisons (3 comparisons: p<0.0167).

The p-value is empirically calculated based on the rank of r²-value in 1,000 simulations.
