Comparison of bulla size relative to the presence of tension pneumothorax. Among patients without fibrotic adhesion, the bullae were larger in the tension pneumothorax group than in those without tension pneumothorax (15.2 ± 12.7 mm vs 9.8 ± 11.2 mm, P = 0.025). However, in cases where fibrotic adhesion was present, the size of the bullae did not differ significantly between the groups (32.0 ± 15.1 mm vs 36.3 ± 24.8 mm; P = 0.323). ns, not statistically significant; * P 0.05.
