From: Non-linear Equation using Plasma Brain Natriuretic Peptide Levels to Predict Cardiovascular Outcomes in Patients with Heart Failure

Figure 3

The Kaplan-Meier plots of calculated and actual cardiovascular event-free rate in patients with plasma BNP levels ≤ 200 pg/mL (A), 200 pg/mL <BNP ≤ 500 pg/mL (B) and BNP levels>500 pg/mL (C). These two lines in each group are significantly close, and the coefficients of determination in A–C are 0.94, 0.90 and 0.96, respectively. Figure (D) shows Kaplan-Meier plots of three calculated cardiovascular events-free rates in the sets of the patients with the plasma BNP levels ≤ 200 pg/mL, 200 pg/mL <BNP ≤ 500 pg/mL and BNP levels>500 pg/mL.
