Initial models adjusted for demographic factors; additional models also controlled for health status and behaviors.then Wald tests from logistic regression models that took vital status SES-mortality relations. Proportional hazards regression can be used to quantify the impact of education, income, and occupational prestige on mortality while adjusting for other covariates, and Wald tests can be used to test the statistical significance of these associations. Survival time of the patients is to be calculated. Additional stratification by age, race, marital status, and urban/rural residence should also be seen.

These might be helpful....
