Expression values for a gene pair ALOX15B~NPY deemed to be DC by our paper's meta-analysis are plotted using data from two prostate cancer datasets in (a) and (b). Non-cancerous subjects are in purple (dots) and cancerous subjects are in orange (triangles). A ‘robust’ regression line is superimposed for each condition (cancerous is dashed). In (c) and (d), relationships within and across conditions for a network of 12 genes greedily built up from a seed of PARM1 are shown. Deepness of color indicates strength of evidence of DC, where correlations of magnitude ≥0.5 are given the deepest hue of red (+) or blue (−); magnitudes ≤0.25 have been hidden
