borderline significancep = 0.0566
In this context, in the model that jointly considers GINI and FPI as causal variables ( p < 0.0001), GINI had a significant individual effect on FI ( p = 0.0486)*; however, contrary to our expectation of FPI being a mediator in the baseline model, we found that FPI did not have a statistically significant effect ( p = 0.0566; borderline significance).
