(): reference category. Significant at <0.000, 0.01, and 0.05, respectively; #COR calculated from the bivariate logistic regression; ##AOR calculated from the multivariate logistic regression. Note: if, in the bivariate analysis, the variable was insignificant, it was not included in the multivariate analysis. Fitting null model for pseudo- (pseudo- was calculated by using the “Pscl” package). IIH: . IIhNull: the . G2: minus two times the difference in the . McFadden: . ML: . CU: . The multicollinearity was assessed by using VIF (variance infection factor) by using “car” package; all the VIF were less than 5. So, there is no multicollinearity in this model.
