Figure 3. Illustration of the final piecewise structural equation model: Fisher’s C = 10.302 (d.f. = 8, P = 0.244) and AICc = 54.302. Numbers on arrows are standardized path coefficients (scaled by their mean and standard deviation), while asterisks indicate statistical significance (***P < 0.001; **P < 0.01; *P< 0.05). Solid red arrows indicate positive relationships, solid blue arrows negative relationships, and gray arrows insufficient statistical evidence for a path coefficient (P > 0.05). Arrow width is indicative of the strength of the causal relationship, and the marginal R2 is shown.
