Figure 1. Cumulative Incidence of Sudden and/or Arrhythmic Death (SAD) and Non-SAD Across Left Ventricular Ejection Fraction (LVEF) and New York Heart Association (NYHA) Functional Class.

The 4-year cumulative incidence of each mode of death (ie, SAD and non-SAD), accounting for the competing risk of death, are shown in strata of LVEF (A and B) and NYHA functional class (C and D). Differences in cumulative incidence across strata are shown (Gray P value).
