Table 1. Values are given in ng/L, except for ICAM-1, IGFBP-6, PARC and RANTES for which concentrations are given in µg/L.When comparing AD vs 1) Controls, 2) Depression and 3) other dementias the following significant changes were observed:aAD vs control p = 0.01,bAD vs depression pcAD vs depression p = 0.034.dAD vs control peAD vs depression p = 0.001.fAD vs control p = 0.004.gAD vs control phAD vs control p = 0.011 (Kruskal–Wallis one-way analysis of variance by ranks followed by Mann-Whitney U test).Abbreviations: Depr, depression; AD, Alzheimers disease; FTD, frontotemporal lobe dementia; VaD, vascular dementia; PDD, Parkinson's disease with dementia; DLB = dementia with Lewy bodies.
