Scoring performances (%) of the blinded raters (n=5) for the presence of nCLE criteria of malignancy or airway/lung parenchyma based on two validation sessions with 28 nCLE videos from 23 patients (total of 280 ratings)
| Sensitivity | Specificity | Accuracy | PPV | NPV | |
| Validation sessions combined | 95.5 | 93.8 | 95 | 97.4 | 89.3 |
| Validation session 1 | 92.9 | 97.5 | 93.6 | 98.9 | 83 |
| Validation session 2 | 99 | 90 | 96.4 | 96.1 | 97.3 |
nCLE, needle-based confocal laser endomicroscopy; NPV, negative predictive value; PPV, positive predictive value.
