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.
