A Network-Based Approach to Investigate the Pattern of Syndrome in Depression

Figure 5

Symptom networks for 7 syndromes in depression. (a) BD (blood deficiency) symptom network. (b) BS (blood stasis) network. (c) FH (fire hot) network. (d) PH (phlegmatic hygrosis) network. (e) QD (Qi deficiency) network. (f) QS (Qi stagnation) network. (g) YD (Yin deficiency) network. Only top 12 key symptoms for each syndrome are employed to construct a corresponding symptom network. All edges are weighted by wMIs of symptom pairs that are not less than 0.1. The red edges indicate that wMIs of corresponding symptom interactions are greater than in random (), while the blue edges represent symptom interactions with less wMIs than in random (); the remaining edges (gray edges) are not statistically significant. A large node implies a high rank for classifying a certain syndrome.
