Table displays results of one model for each of the five OHRQoL dimensions. Each model is based on backward stepwise multivariate logistic regression predicting the yes-no outcome for each of the five dimensions (Stata 10). Variables shown in each model were those retained as statistically significant at p < 0.05.
