TABLE 2.

Pairwise comparisons of positive/negative outcomes among groups and relative p‐values.

Comparison	p‐value fisher	adj. p‐value LR
PD/DLB versus CTRL	< < 0.00001	< < 0.00001
PD/DLB versus AD	< < 0.00001	< < 0.00001
AD versus CTRL	0.00010	0.0015
pre‐AD+MCI‐AD versus AD‐dem	0.11	0.089
pre‐AD+MCI‐AD versus CTRL	0.0030	0.0050
typical/amnestic versus lv‐PPA	0.14	0.12
typical/amnestic versus PCA‐AD	0.0059	0.013
lv‐PPA versus PCA‐AD	0.0018	0.0037

Note: p‐values were determined both by Fisher exact test for numerical data and by logistic regression (LR) by assuming age and sex as covariates (adj. p‐value).

Abbreviations: AD, Alzheimer's disease; AD‐dem, Alzheimer's disease at dementia phase; CTRL, controls; DLB, dementia with Lewy bodies; lv‐PPA, logopenic variant of primary progressive aphasia AD presentation; MCI‐AD, mild cognitive impairment due to AD; PCA‐AD, posterior cortical atrophy AD clinical presentation; PD, Parkinson's disease; pre‐AD, preclinical Alzheimer's disease; typical/amnestic, typical/amnestic AD clinical presentation.
