Table 2 Regional AV-45 uptake

	AV-45-PET values
	Patients’ mean SUVr (±sd)	Control subjects’ mean SUVr (±sd)	p value
Global cortex	1.43 (±.29)	1.15 (±.08)	.002**
Orbito-frontal	1.60 (±.41)	1.23 (±.16)	.001**
Anterior cingulate	1.67 (±.41)	1.30 (±.16)	.003**
Posterior cingulate	1.74 (±.36)	1.36 (±.14)	.002**
Precuneus	1.56 (±.36)	1.14 (±.09)	.002**

AV-45 mean regional-to-cerebellum standard uptake values (SUVr) with associated standard deviation (sd) are mentioned for the global cortex and specific regions of interest for the two groups. **p < .01 (significant inter-group difference on the Mann–Whitney test, Bonferroni-Holmes-corrected).
