---|---|---|---|---|---|---|
Age | NT-proBNP | Sens | Spec | NT-proBNP | Sens | Spec |
45–54 yrs | 108 | 100 | 96 | ND | ND | ND |
55–64 yrs | 234 | 100 | 94 | 246 | 100 | 90 |
65–74 yrs | 462 | 91 | 94 | 773 | 100 | 98 |
≥75 yrs | 1,024 | 89 | 84 | 879 | 75 | 86 |
Cutpoints are based on optimal discriminatory value obtained from stratum-specific ROC curves.
ND = not determined; NT-proBNP = amino-terminal pro-B-type natriuretic peptide; Sens = sensitivity; Spec = specificity.
