Figure 5

Data structure found in the input space of d = 43 lipid marker serum concentration acquired from patients with multiple sclerosis and from healthy controls. The data structure has been obtained by means of data projection principal component analysis on the non-normalized data as suggested by the results of the PC-corr analysis102. The PCA plot associated to this analysis shows the sample separation in the first and fourth component (PC1 versus PC4); the fourth component was chosen as it yielded the best explained variance for unnormalized, centered PCA after the first one. The figure has been created using the R software package (version 3.4.2 for Linux; http://CRAN.R-project.org/)43, an R script provided with the description of the PC-corr analysis (pccorrv2.R, https://github.com/biomedical-cybernetics/PC-corr_net)102.
