View larger version (16K): [in a new window]   Figure 2 Tree diagram illustrating the mortality risk for octogenarians stratified according to the independent predictors defined from the multivariable model. Patients are included into only one risk group in a hierarchical manner (considering the presence of each risk factor in descending order of predictive importance). The observed mortality and corresponding 95% CIs are presented at the bottom.

View larger version (19K): [in a new window]   Figure 3 The relative odds of procedural success and in-hospital adverse events (death, death/MI/CVA and vascular complications) are expressed as adjusted OR with 95% CI for each year from 1995 through 1997, as compared with the first year of data collection (1994). The ORs presented have been adjusted for the seven variables in the multivariable mortality risk model.
