Figure 6:

(A) Generational airway counts for reference (solid) and test (dotted) airway segmentation for multiprotocol (red) and multiscanner (green) generalizability experiments together with reference counts at standard-dose CT (gray line) for the accuracy experiment. (B) Relative performance for the multiprotocol (red) and multiscanner (green) generalizability experiments at low-dose CT. II Stand = the method trained and evaluated on standard-dose CT scans from phase II visits of the Genetic Epidemiology Chronic Obstructive Pulmonary Disease (COPDGene) Iowa cohort (CII-Stand); N Low (Ref) = the method trained and evaluated on low-dose chest CT scans from the DutchEN_DASHBelgian Randomized Lung Cancer Screening trial (NLow); N Low (Test) = the method trained on CII-Stand and evaluated on NLow; III Low (Ref) = the method trained and evaluated on low-dose chest CT scans from phase III visits of the COPDGene Iowa cohort (CIII-Low); III Low (Test) = the method trained on CII-Stand and evaluated on CIII-Low; Data NLow = the method trained on CII-Stand and evaluated on NLow, Data CIII-Low = the method trained on CII-Stand and evaluated on CIII-Low.
