Figure 3 Kaplan-Meier Survival Curves According to Summed Stress Score Risk Categories
Kaplan-Meier estimates for overall survival in atrial fibrillation (AF) patients (A) and non-AF patients (B) according to summed stress score (SSS) risk categories. Survival difference was statistically significant in both AF and non-AF patients (p < 0.001 by log rank statistic). Numbers below the graphs indicate numbers of patients available for analysis at given time points.
