Figure 4.

Voxel-wise comparisons of grey matter volumes between combined behavioural/dysexecutive variant Alzheimer’s disease, typical Alzheimer’s disease and behavioural variant FTD patients. Contrasts were adjusted for age, sex, total intracranial volume, scanner type and centre. Results are superimposed on the SPM8 single-subject template (left) and the study-specific DARTEL template (right), and displayed at P < 0.001 uncorrected. Supplementary Table 1 includes the coordinates of local maxima and their anatomical labels, T-values, P-values and cluster sizes.
