Figure 1From: B-type natriuretic peptide versus amino terminal pro-B type natriuretic peptide: selecting the optimal heart failure marker in patients with impaired kidney function Scatter plot of log transformed plasma B-type natriuretic peptide (BNP) and amino terminal B-type natriuretic peptide (NT-proBNP) in relation to estimated glomerular filtration rate (eGFR). Lines of best linear fit are drawn.Back to article page
