Overview of regression analysis oPLS-DA score and variables importance in projection (VIP) score plots of the CSF metabolites between Alzheimer’s disease (AD), controls (Con) and mild cognitive impairment (MCI) (AD; n = 29, Con; n = 20, MCI; n = 22) in the CSF cohort: (A–C) oPLS-DA and VIP score plots of the CSF metabolites between the groups AD and Con, MCI and Con; AD and MCI. In the VIP scores plot each box is representing a group mean value in a form of color gradient (red—high concentration, blue—low concentration). PC, phosphocholine; AD, Alzheimer’s disease; MCI, mild cognitive impairment; Con, control subjects; CSF, cerebrospinal fluid.
