Accuracy of meta-feature signatures involving differences in analyte abundances in classifying controls and MCI progressors.

aThe full set of samples contained data on 54 Controls and 163 MCI Progressors. bThe size-matched groups contained data on 54 Controls and 54 MCI Progressors. For each of these datasets, all samples were used for cross-validation, whereas training and test sets were created by dividing datasets into two equal subsets.
