Figure 1 Subgroup analyses-risk of mortality related to taking of the exercise test (EXT). Five-year estimated survival rates for important patient subgroups. The 99% confidence intervals (CI) of the difference between the five-year survival for patients who took the EXT and those who did not are shown. CHF = congestive heart failure; PVD = peripheral vascular disease.
