  2. *-- p < 0.05; **-- p < 0.01; ORu-- univariate odds ratio; ORm- multivariate odds ratio obtained from multivariate stepwise logistic regression; NA: not chosen for multivariate logistic regression analyses as the factor was statistically non-significant in the univariate logistic regression analysis; NS: not statistically significant in the multivariate logistic regression. Variables that were significant in the p < 0.05 level were bolded.
