The area of scar as seen by optical coherence tomography (OCT) and histologic examination was evaluated by blinded investigators. The x-axis shows the rabbit numbers. Airway scarring measured by fractional airway area measurements ranged from 9% to 34% as identified by OCT, and 23% to 43% by histologic images. Among OCT experts, the area of stenosis was consistently identified within a standard error of 2.8%, and among histology experts, the area of stenosis was consistently identified within a standard error of 3.2%. Error bars indicate standard errors.
