Prospective multi-centre Voxel Based Morphometry study employing scanner specific segmentations: Procedure development using CaliBrain structural MRI data

Table 2 Grey matter metric results for the subjects excluded from priors generation

Scanner Comparison	Baseline*	Adjusted*	Mean Difference (paired sample significance)
AA	2.8 (0.6)	2.8 (0.6)	0.00 (p < 1.00)
BB	3.4 (0.6)	3.4 (0.6)	0.00 (p < 1.00)
CC	2.6 (0.7)	2.5 (0.7)	0.05 (p < 0.078)
AB	7.3 (0.6)	5.1 (0.7)	2.2 (p < 0.001)
BC	8.2 (0.8)	5.5 (0.8)	2.7 (p < 0.001)
AC	4.0 (0.6)	3.6 (0.5)	0.36 (p < 0.003)

Grey matter metric results averaged over the seven subjects excluded from the scanner specific priors adjustment procedure. For the within and between scanner comparisons both baseline and adjusted absolute percentage distances are recorded.
