Figure 1 Survival Curve for Freedom From Cardiovascular Death
Kaplan-Meier event-free survival curves relative to the primary end point (cardiovascular death) in the 2 groups of patients. Broken red line = patients with depressed baroreflex sensitivity (BRS); solid green line = patients with preserved BRS.

Figure 2 Occurrence of Cardiovascular Death on the Basis of Age and BRS
Cardiovascular mortality on the basis of baroreflex sensitivity (BRS) in the different age groups. The number of patients in each group is listed below the bar. Red bars = patients with depressed BRS; green bars = patients with preserved BRS.

Figure 3 Survival Curve for Freedom From All-Cause Mortality
Kaplan-Meier survival curves in the 2 groups of patients for total mortality. Broken red line = patients with depressed baroreflex sensitivity (BRS); solid green line = patients with preserved BRS.
