Supplementary Figure 4: Weak relation between cytokine connectivity degrees and historical knowledge accumulation.

The correlation of the cytokine degree and the date of first publication was repeatedly computed across cytokines, threshold by minimal degree. A scatter plot showing this correlation when scaled back from the entire network to only few highly dominant hubs (cytokine degree cutoff is shown along x-axis). The entire network (n=145 cytokines) demonstrates low correlation, r=-0.27 and -0.26, Pearson's for (a) incoming and (b) outgoing interactions respectively, driven by a few highly dominant hubs.
