Figure 6.
(A) PCA analysis for the field samples representing the distribution of lesion samples of GS 1, GS 2 and treated groups. Analysis was based on fold-changes of all genes for each individual sample (smaller symbols) relative to GS 0. The ellipses indicate the group dispersion/variability from the centroid (larger symbols) calculated using all individual fold-changes values. (B) PCA analysis for the field samples representing the distribution of lesion and non-lesion samples of GS 1, GS 2 and treated groups. Analysis is based on fold-changes of all genes for each individual sample relative to GS 0. For clarity, individual values were omitted from the plot and only the group centroids were plotted.
