Multivariate analyses regarding the risk factors of pulmonary and overall recurrence

Characteristics	Pulmonary recurrence		Overall recurrence
	HR (95% CI)	P value	HR (95% CI)	P value
p/ypTNM stage (II/III vs 0/I)	8.823 (2.134 to 36.475)	0.003	5.084 (2.348 to 11.009)	<0.001
Circumferential margin (≤1 vs >1 mm)	3.127 (1.503 to 6.506)	0.002	2.032 (1.081 to 3.820)	0.028
Tumour location (<5 vs ≥5 cm)	1.955 (1.104 to 3.463)	0.022	1.376 (0.906 to 2.090)	0.134

TNM, tumor-node-metastasis; yp, pathological stage after neoadjuvant therapy.
