Psychological consistency network characteristics and influencing factors in patients after percutaneous coronary intervention treatment

Figure 1 Network structure diagram of sense of coherence scale-13 symptoms in patients after percutaneous coronary intervention. A: Symptoms network of sense of coherence scale-13 (SOC-13) in patients after percutaneous coronary intervention (PCI). The edge between the two connected nodes represented their association strength. Wherein, the blue indicated positive association, red showed negative correlation. And the shorter and darker the edges were, the stronger their association were; B: Centrality analysis of SOC-13 symptoms in patients after PCI. Closeness is the inverse of the sum of the shortest path distances from all other nodes to that node, betweenness is the frequency of a node being on the shortest paths of any two other nodes, and strength is the sum of the weighted values of all the connecting lines of a node. The higher the score of point degree centrality of a symptom, the more central the symptom is in the network, i.e., it is the core symptom in the network; C: Stability coefficients for the expected impact of symptoms. The stability coefficient for the expected impact of symptoms was > 50, representing the model was stable. SOC: Sense of coherence.

Figure 2 Marginal weighting analysis of sense of coherence scale-13 symptoms in post-percutaneous coronary intervention patients. A: Marginal weighting analysis of sense of coherence scale-13 symptoms in post-percutaneous coronary intervention patients. Edge-weights were ordered from strong to weak, top to bottom. Grey area indicated the bootstrapped confidence intervals for each edge; B: Marginal difference test results for sense of coherence scale-13 symptoms in patients after percutaneous coronary intervention. Black boxes indicate significant difference, while gray boxes indicate non-significant difference between edges located on the corresponding X and Y-axis. The color of diagonal boxes indicated the strength and direction of its corresponding edge. Blue indicates positive and red indicates negative edge. Darker color indicates stronger edge. More numbers of black boxes with regard to an edge indicate that it is significantly stronger than most other edges. SOC: Sense of coherence.
