Ranking-PCA applied to the 395 selected variables to compare PD patients and HCs. a. Representation of the samples along the first canonical root. The first canonical root (y-axis) is reported for each sample (x-axis). Blue circles correspond to control samples while red circles to pathological samples. The solid line represents the separation between the two classes. The variables are reported in Additional file 3 in the order in which they are included in the model. b. Functional annotation analysis of the 395 variables. Over-represented GO annotations with at least 10 genes and P < 0.02 (Fisher exact probability) are presented. The complete data of enriched GO annotations are available in Additional file 5
