Table 5. Comparison of pulmonary function between SS ≤5 vs. SS ≥6 groups.

Pulmonary function	SS ≤5 (n=32)	SS ≥6 (n=24)	P value
FVC (%)
Baseline	101 (65.0, 136)	99.2 (70.7, 115)	0.46
Postoperatively	93.4 (44.5, 127)	84.8 (56.4, 112)	0.23
Change from baseline	−11.0 (−50.8, 15.3)	−9.50 (−36.5, 6.30)	0.60
FEV1 (%)
Baseline	95.2 (51.4, 127)	89.2 (67.2, 119)	0.47
After surgery	87.3 (41.5, 122)	73.1 (45.5, 105)	0.29
Change from baseline	−7.95 (−26.0, 11.3)	−9.75 (−29.3, 11.8)	0.28

Data are expressed as median (range). FEV1, forced expiratory volume in 1 second; FVC, forced vital capacity; SS, subsegments.
