| V-VST | ||||||
|---|---|---|---|---|---|---|
| Sensitivity (95% CI) | Specificity (95% CI) | PPV | NPV | LHR+ | LHR− | |
| OD | 0.94 (0.87–0.98) | 0.88 (0.50–0.99) | 0.98 | 0.70 | 7.83 | 0.068 |
| Impaired efficacy | 0.79 (0.62–0.90) | 0.75 (0.45–0.92) | 0.93 | 0.67 | 3.16 | 0.280 |
| Impaired safety | 0.87 (0.74–0.94) | 0.81 (0.48–0.95) | 0.93 | 0.46 | 4.58 | 0.160 |
| Aspirations | 0.91 (0.78–0.99) | 0.28 (0.17–0.34) | 0.21 | 0.94 | 1.26 | 0.321 |
CI, simultaneous confidence interval; PPV, positive predictive value; NPV, negative predictive value; LHR, likelihood ratio; OD, oropharyngeal dysphagia.
