Figure 2 Kaplan-Meier Analyses
Kaplan-Meier curves showing the incidence rate of readmission for decompensated heart failure or sudden death (A) or of readmission alone (B) according to 6-month post-discharge B-type natriuretic peptide (BNP) ranges. B-type natriuretic peptide ranges were <190 (the best cutoff level for predicting readmission or sudden death), 190 to 380, and >380 (its 2-fold level) pg/ml. p < 0.0001 (the log-rank test) versus a BNP range of <190 pg/ml.
