This model is adjusted for variables with estimates presented in the relevant columns and includes all significant co-morbidities using a stepwise selection process with a p < 0.1 for entry and a p < 0.05 for retention in the model. Results delineated in bold refer to statistically significant variables relative to the reference group (ref) at p < 0.05. When income was introduced in the model, education became nonsignificant and was dropped from the model
