Notes: Asterisks represent statistically significant at the levels: *p ≤ 0.1; **p ≤ 0.05; ***p ≤ 0.01; n.s., not statistically significant. Brant tests have verified that the proportional odds assumption (or the parallel regression assumption) was not violated for the two regression models. To exclude multicollinearity issues, correlation matrixes were computed and the variance inflation factor (VIF) was calculated to check potential correlations among independent variables of both models. Falsification tests were also performed, finding no significant effects of the control variables on alternative outcomes
