- 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.
