Survival Curve from Scientific Research

KaplanMeier curves for mortality in patients aged 80 years or older. The KaplanMeier curves showed significantly different mortality rates in different ejection fraction categories stratified by age group. HFmrEF=heart failure with mildly reduced ejection fraction. HFpEF=heart failure with preserved ejection fraction. HFrEF=heart failure with reduced ejection fraction.
