Scores generated from (A) PCA of ¹H NMR in vacuo, (B) PCA of DI-ESI-MS in vacuo, and (C) MB-PCA of ¹H NMR and DI-ESI-MS. Separations between classes are greatly increased upon combination of the two datasets via MB-PCA. Symbols designate the following classes: Control ( ), Rotenone ( ), 6-OHDA ( ), MPP+ ( ), and Paraquat ( ).Corresponding dendrograms are shown in (D–F). The statistical significance of each node in the dendrogram is indicated by a p value (Worley, Halouska, Powers 2013).
