Results of co-expression analysis for the competitive (A) and self-contained null models (B). The x-axis indicates the co-expression of a specific gene set and the y-axis indicates the probability of significance for a specific gene set (Psig-G). Each dot denotes a specific gene set with the lighter color denoting the larger size of the gene set. The horizontal dashed line denotes a Psig-G of 0.05. The tests are carried out at a nominal α = 0.05 significance level and the horizontal dashed line denotes a Psig-G of 0.05.
