% refer to the percentage in each stratum. Raw OR: Odds Ratio resulting from bivariate analysis. Adjusted OR: Odds Ratio for significant variables (p ≤ 0.05) in bivariate analysis through a multivariate logistic regression model. CI: confidence interval. Ref. = reference category. 'High score' implies scores higher than the upper quartile of the scores observed in the sample', 'low score' implies scores lower or equal than the upper quartile.
