^aNR ²= Nagelkerke’s R squared which estimates strength of association between predictors in each step for the hierarchical logistic regression.

^bOR=Odds Ratio which is an estimate of effect size for each predictor from the final hierarchical logistic regression model generated.

^c95th CI = 95^th Confidence Interval for each predictor from the final hierarchical logistic regression model generated.

^dR² =indicates the amount of variance accounted for by each additional step in the hierarchical linear regression.

^eβ =standardized beta estimates for the final hierarchical linear regression model generated are presented as an estimate of effect size.
