A multidimensional scaling plot of psoriasis datasets from Gudjonnson et al. 2010 [18] (A) and Yao et al. 2008 [36] (B) to illustrate grouping of samples according to random forest clustering. Two distinct psoriatic groups are identified in involved tissue (PP01 green and PP02 purple), while NN and PN samples largely co-localise. Overall, clustering is comparable to GAIN data that is shown in figure 4.
