To detect factors associated with cardiovascular mortality in the elderly of Botucatu.

We evaluated 29 variables of interest in a cohort of patients aged 60 using data from a survey conducted between 1983/84. The elderly cohort was analyzed in 1992 to detect the occurrence of cardiovascular deaths. Survival analysis was performed using the Kaplan-Meier method, the log-rank test, and Cox regression analysis. Three models were adapted for each group of variables, and a final model was chosen from those variables selected from each group.
