Figure 2 Time-Dependent Receiver-Operator Characteristic Curves for All-Cause Mortality

Curves are based on univariate models of the prediction of risk at 24 months with single determinations of NT-proBNP at baseline or 4 months or as percentage relative or absolute changes from baseline. Areas under the curves were compared with the C-index. NT-proBNP = N-terminal pro-brain natriuretic peptide.
