Fig 1 Kaplan–Meier curve showing the probability of survival after surgery, stratified by the median NT-proBNP level for this cohort (289 ng litre−1). Data presented as survival probability over 3 yr with confidence intervals (dashed lines). Number at risk also presented at each time point.

Fig 2 Kaplan–Meier curves showing the probability of survival after isolated CABG surgery (a) and after valve, aortic, or both surgery (±CABG surgery) (b), stratified by the median NT-proBNP level for each group. Data presented as survival probability over 3 yr with CIs (dashed lines). Number at risk also presented at each time point.
