3. Figure 2
Adjusted survival curves by Cox regression for subjects with exercise-based T-wave alternans (TWA) <60 μV and heart rate recovery (HRR) >18 bpm (top curve in both panels), TWA ≥60 μV or HRR ≤18 bpm (middle curve in both panels), and TWA ≥60 μV and HRR ≤18 bpm (bottom curve in both panels) for all-cause mortality (A) and cardiovascular mortality (B). Note that the scale for the y-axis is from 0.75 to 1.00.

Adjusted survival curves by Cox regression for subjects with recovery-based T-wave alternans (TWA) <60 μV and heart rate recovery (HRR) >18 bpm (top curve in both panels), TWA ≥60 μV or HRR ≤18 bpm during recovery (middle curve in both panels), and TWA ≥60 μV and HRR ≤18 bpm during recovery (bottom curve in both panels) for all-cause mortality (A) and cardiovascular mortality (B). Note that the scale for the y-axis is from 0.75 to 1.00.
