Kaplan–Meier curves for infection-related rehospitalization event-free survival in heart failure patients categorized by high hemoglobin (hemoglobin ≥13.2 and ≥12.5 g/dl for men and women, respectively) and low hemoglobin levels (hemoglobin <13.2 and <12.5 g/dl for men and women, respectively) (a), and by estimated glomerular filtration rates of at least 60, 30–60, and of 30 ml/min/1.73 m² or less. ^∗Log rank = 8.9, P = 0.003 compared with estimated glomerular filtration rates at least 60 ml/min/1.73 m². ^†Log rank = 24.7, P < 0.001 compared with estimated glomerular filtration rates at least 60 ml/min/1.73 m².
