Figure 4 Positive predictive value concerning death at 35 months in relation to troponin T and NT-proBNP level on admission. Number of patients in each group is shown on each bar. NT-proBNP = N-terminal pro brain natriuretic peptide; cTnT = cardiac troponin T. Open bars = NT-proBNP < 401 ng/l; solid bars = NT-proBNP > 1,653 ng/l; hatched bars = NT-proBNP 401–1,653 ng/l.
