Figure 5 Relationship of Summed Stress Score and Mortality in the Presence of Atrial Fibrillation
Kaplan-Meier estimates for overall survival in atrial fibrillation (AF) and non-AF patients according to low-/intermediate-risk summed stress score (SSS) and high-risk SSS. Differences between the survival curves of the low-/intermediate-risk SSS AF and non-AF groups as well as between the high-risk SSS AF and non-AF groups were statistically significant (p < 0.001 by log rank statistic for the curves as shown). Numbers below the graph indicate numbers of patients available for analysis at given time points.
