| Variables | AUC | 95% CI | Cut-off point | Sensitivity (%) | Specificity (%) |
|---|---|---|---|---|---|
| BNP | 0.680* | 0.581–0.767 | 170.6 | 100.0 | 43.2 |
| LAP | 0.764* | 0.671–0.842 | 11.8 | 91.7 | 53.1 |
| LUS | 0.781* | 0.690–0.856 | 8.9 | 95.8 | 50.6 |
| Hemidiaphragm dysfunction | – | – | – | 58.3 | 67.9 |
| Combined model | 0.919 | 0.850–0.963 | 0.26 | 91.7 | 82.7 |
| 95% CI – 95% confidence interval; AUC – area under curve; BNP – brain natriuretic peptide; LAP – left-atrial pressure; LUS – lung ultrasound score; compared with the combined model, * | |||||
