Complex Networks Approach for Analyzing the Correlation of Traditional Chinese Medicine Syndrome Evolvement and Cardiovascular Events in Patients with Stable Coronary Heart Disease

Figure 1

Wiring diagrams for the complex networks obtained from clinical data of recurrent cardiovascular events (node degree = 0). Notes: Blood_stasis_baseline represents blood stasis at the baseline and Blood_stasis_6_month represents blood stasis at the 6-month follow-up (the same as in Figure 2). In the network, the nodes of the link present the corresponding syndrome, the links present that at least one patient suffers the syndrome, and the weight of the links equals the number of patients. For example, the weight of link between Blood_stasis_baseline and Qi_deficiency_6_month was 26, which represents the fact that 26 of 30 cases with blood stasis at the baseline transformed to Qi deficiency at the 6-month follow-up.
