Figure 1 Kaplan-Meier estimates of the probability of death (A) and death or congestive heart failure (CHF) (B) through six months among patients with baseline concentration of B-type natriuretic peptide (BNP) >80 pg/ml and 80 pg/ml. The p values are based on the log-rank test.

Figure 2 Mortality risk stratified by B-type natriuretic peptide (BNP) levels over range of 40 to 160 pg/ml. The odds ratio (ORs) and chi-squared ( 2) statistics in the table below the chart are based on BNP results dichotomized at the lower bound of the range.
