The shape of the nodes corresponds to the type of each factor. The color of the edges corresponds to the positive (red), negative (blue) or sole effect (black) relationship. The shape of edges corresponds to the interaction (↔) or effect (→) of the relationship. The full line of the edges corresponds to P < 0.05, and the imaginary line corresponds to P > 0.05.
