Model performance for the MKL and SVM whole brain models distinguishing between ‘demented patients’ (D) and ‘control’ (C)

Model	Atlas	Balanced accuracy (%)	True positives (D)/ Total positives	True negatives (C)/ Total negatives
MKL	AAL	66.00 (p = 0.01)	34/50	32/50
	Brodmann	68.00 (p = 0.01)	34/50	34/50
	HCP	65.00 (p = 0.01)	34/50	31/50
SVM	AAL	67.00 (p = 0.01)	32/50	35/50
	Brodmann	70.00 (p = 0.01)	33/50	37/50
	HCP	63.00 (p = 0.01)	29/50	34/50

True positives (resp. negatives) represent the number of demented (resp. non-demented) patients classified correctly as demented (resp. non-demented). Note that the difference between the SVM models is only the mask used to select the voxels, which is based on the atlas
