Figure 1 Rate of Death by Quartiles of NT-proBNP Changes
Patients were divided according to quartiles of absolute (A) or percent relative (B) changes of NT-proBNP over 4 months and rates of death at end point are shown. Absolute changes were calculated as NT-proBNP4-month – NT-proBNPbaseline. Relative changes were calculated as 100 x ([NT-proBNP4-month – NT-proBNPbaseline]/NT-proBNPbaseline). Number of events and total number of patients for each quartile are shown above the bars. NT-proBNP = N-terminal pro-brain natriuretic peptide.
