Fig. 3From: Machine learning can predict survival of patients with heart failure from serum creatinine and ejection fraction aloneScatterplot of serum creatinine versus ejection fraction. Serum creatinine (x axis) range: [0.50, 9.40] mg/dL. Ejection fraction (y axis) range: [14, 80]%. We manually drew a black straight line to highlight the discrimination between alive and dead patientsBack to article page
