Figure 2: Kaplan-Meier event-free curves of two groups classified by cutoff values of Hb level of 11.9 g/dL (left panel) and eGFR of 47.5 ml/min/1.73 m2 (right panel) after adjustment using New York Heart Association functional class, dyslipidemia, drug use, and BNP concentration. Patients with Hb level less than 11.9 g/dL or eGFR less than 47.5 ml/min/1.73m2 (red line) had significantly lower event-free rates than did patients with Hb level or eGFR not less than those values (blue line).
