Parenthetical values reflect 95% confidence intervals. Unadjusted odds ratios and their associated significance (

*P*) values reflect bivariate relationships between each predictor and group membership. Demographically adjusted odds ratios and*P*values reflect those relationships after covarying for gender, race, and socioeconomic status (unless the predictor is 1 of these 3 demographic factors, in which case the remaining 2 covariates were entered). Full-model odds ratios and*P*values reflect the predictor group associations after adjusting for all other variables in the table.
