Supplementary Figure 4. Kaplan-Meier curves of 12-month readmission free survival rates according to renal dysfunction with subclassification in all (A), HFpEF (B) and HFrEF (C) patients. GFR = glomerular filtration rate; HFpEF = heart failure with preserved ejection fraction; HFrEF = heart failure with reduced ejection fraction. Supplementary Figure 4.
