Corresponds to the sum of the three control groups (AD, PSP and BP patients).
2
The first comparison was performed between the four groups of patients (bvFTD, AD, PSP and BP) while the second analysis compared bvFTD patients to all controls (AD, PSP and BP patients as a whole). p values <0.05 were considered significant and are written in bold.
