Evaluation results on the independent and partially AV-labelled dataset of clinical noncontrast CT cases. Mean F1-score values [0–100] and standard deviations are reported in the three evaluation stages categorized by the quality of the airway tree segmentation as Complete, Partial and Incomplete.

Complete (10 cases)	79.3 ± 4.8	56.1 ± 2.1	79.8 ± 6.2	83.0 ± 6.2
Partial (7 cases)	76.0 ± 6.2	53.8 ± 3.3	76.8 ± 10.3	79.1 ± 9.4
Incomplete (3 cases)	72.6 ± 10.5	53.3 ± 1.5	70.1 ± 8.9	71.4 ± 8.9
All	76.9 ± 6.6	54.6 ± 2.8	77.0 ± 8.7	79.5 ± 8.6
