Comparison of postoperative complications between segmentectomy and lobectomy by video-assisted thoracic surgery: a multicenter study

Table 3 Logistic regression models for the occurrence of any complication, and of a cardiopulmonary complication

Models		Any complication		Cardiopulmonary complication
Models		OR (95% CI)	P	OR (95% CI)	P
1	VATS segmentectomy^a	0.91 (0.61–1.30)	0.58	0.93 (0.65–1.34)	0.71
1	Propensity score^b	0.42 (0.16–1.17)	0.10	0.46 (0.19–1.13)	0.049
2	VATS segmentectomy^a	0.93 (0.70–1.24)	0.62	0.86 (0.60–1.24)	0.41

Model 1: standard logistic regression, where the propensity score was left as a continuous probability between 0 and 1. Model 2: Conditional logistic regression, with 15 sets matched for propensity (0.100–0.149, 0.150–0.199, 0.200–0.249, etc). Fifty-five patients with a propensity for segmentectomy < 0.10 and > 0.85 were excluded, as all were treated with the same intervention. ^a vs lobectomy
^b probability of 1 vs 0
