A Dynamic Network Approach for the Study of Human Phenotypes
Figure 2
Phenotypic Disease Networks (PDNs).
Nodes are diseases; links are correlations. Node color identifies the ICD9 category; node size is proportional to disease prevalence. Link color indicates correlation strength. A. PDN constructed using RR. Only statistically significant links with RRij>20 are shown. B. PDN built using φ-correlation. Here all statistically significant links where φ>0.06 are shown.
