Figure 2. Kaplan-Meir estimates for survival stratified by trends in NT-proBNP. Left Panel: HF -Downtrending NT-proBNP(>=25% decrease in NT-proBNP from initial value, red line) or stable NT-proBNP(green, change less than 25% of initial level) and up-trending NTpro-BNP(>=25% net rise in NT pro-BNP, blue line) .Middle panel: HFpEF - uptrending NT-proBNP (red line), downtrending or stable NT-proBNP (light blue line). Right Panel: HFrEF - uptrending NT-proBNP(red line), downtrending or stable NT-proBNP (light blue line) . p-values are reported for the logrank test.
