Table 1 Demographic and biochemical data

From: Plasma tau levels in Alzheimer's disease

  AD (n= 54) MCI (n= 75) Controls (n= 25)
Age, years 75 (6.2) 68 (9.3) 74 (6.7)
Gender, male/female 17/37 29/46 6/19
MMSE, score 19 (4.9)a 27 (1.6) 29 (1.4)
Plasma T-tau, pg/mL 8.80 (10.1)b,c 4.68 (4.25) 4.43 (2.83)
CSF T-tau, pg/mL 828 (375)a 550 (421) 507 (254)
CSF P-tau, pg/mL 123 (49.2)a 78.1 (28.8) 73.4 (20.5)
CSF Aβ42, pg/mL 380 (87.6)a 478 (204) 584 (215)
  1. Quantitative data are presented as mean (standard deviation). Statistical differences were determined by using nonparametric tests. Cerebrospinal fluid (CSF) biomarker concentrations are INNOTEST ELISA-normalized Luminex AlzBio3 (Innogenetics, Gent, Belgium) values. aCompared with patients with mild cognitive impairment (MCI) or controls, P <0.001. bCompared with patients with MCI, P = 0.001. cCompared with controls, P = 0.02. AD, Alzheimer's disease; MMSE, mini-mental state examination.
