Cumulative incidence curves for time to cardiovascular death or heart failure hospitalization (top panel) and recurrent heart failure hospitalization (bottom panel) in the placebo group, according to ejection fraction subgroup. Shown are subgroups based on ejection fractions of <25%, 25–34%, 35–44%, 45–54%, 55–64%, and 65% or greater. There was an inverse relationship between baseline ejection fraction and the risk for serious heart failure outcomes.
