Postoperative complications in patients who underwent lobectomy or partial resection of the lung to which AFL independently contributed

Response variable	Odds ratio for AFL (95% CI)	P value*
Respiratory failure including LTOT	2.14 (1.12–4.11)	0.0214
Atelectasis	1.90 (1.19–3.01)	0.0063

^*Multivariate logistic regression analysis was utilized in each response variable (odds ratio for AFL as the explanatory variable was adjusted by age, sex, history of smoking, and postoperative complications except for a response variable of interest). AFL: airflow limitation; LTOT: long-term oxygen therapy; 95% CI: 95% confidence interval
