Notes: b = unstandardized partial regression coefficient; SE = standard error for the regression coefficent; AOR = adjusted odds ratio; 95% CI = 95% Confidence Interval for the adjusted odds ratio; η2 = semi-partial η2 (a measure of the unique variance in the outcome measure explained by the effect of interest); p = p-value associated with the test of the regression coefficient. AORs and 95% CIs are reported for logistic and Poisson regression analyses, while η2 is reported for ordinary least squares analyses. In the case of logistic regression analysis, the reference group is indicated in [brackets].
