Note: *** p < 0.01; ** p < 0.05; * p < 0.1. dp/dx show the first derivative of the response variable (in terms of probability) with respect to the covariate, for factor levels is the discrete change from the reference level. Standard errors using in the 95% confidence interval of the effect (95% CI) are obtained by the delta method
