A multidimensional scaling plot of psoriasis datasets from Gudjonnson et al. 2010  (A) and Yao et al. 2008  (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.
