BNP thresholds to predict mortality.
| Cut-off BNP (pg/mL) | Sensitivity (%) | Specificity (%) | LR+ (%) | LR− (%) |
|---|---|---|---|---|
| 100 | 76.5 | 60.8 | 1.95 | 0.39 |
| 200 | 58.8 | 75.8 | 2.43 | 0.54 |
| 224.1* | 58.8 | 80.8 | 3.07 | 0.51 |
| 300 | 47.1 | 87.5 | 3.76 | 0.61 |
BNP, B-type natriuretic peptide; LR+, positive likelihood ratio; LR-, negative likelihood ratio.
*The best calculated cut-off.
Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio at different cut-off levels.
