Summary of study 1 results: wall area % in different lung regions (samples “A”-“E”). Significant wall thickening (increased wall area %) was detected in sample “A”, sample “D” and sample “E”. As previously described [21], sample “A” was collected from the lung apex, sample “B” at the emergence of the main bronchus, sample “C” from the center of the main lung lobe, sample “D” from the caudodorsal part of the main lung lobe and sample “E” was collected from the peripheral caudodorsal part of the main lung lobe and corresponds to the specific biopsy site during thoracoscopy.
