Univariate and multivariate analyses of risk factors on prognosis in OLCCs.

OLCCs	3-year DFS				3-year OS
	Univariate		Multivariate		Univariate		Multivariate
Characteristic	Hazard ratio (95% CI)		Hazard ratio (95% CI)		Hazard ratio (95% CI)		Hazard ratio (95% CI)
Age (≥60 vs <60 years)	1.90 (0.64, 5.68)	0.251	—	—	1.75 (0.62, 4.92)	0.288	—	—
Sex (male vs female)	1.13 (0.42, 3.01)	0.813	—	—	0.52 (0.19, 1.44)	0.205	—	—
ASA ( vs )	0.75 (0.20, 2.88)	0.673	—	—	1.34 (0.42, 4.22)	0.622	—	—
Group (ES vs SEMS)	1.34 (0.51, 3.51)	0.550	—	—	1.58 (0.66, 3.81)	0.308	—	—
pT stage (pT4 vs pT1-3)	3.12 (1.15, 8.48)	0.026	3.88 (1.54, 9.77)	0.004	3.64 (1.31, 10.11)	0.013	4.04 (1.66, 9.86)	0.002
pN stage (pN+ vs pN0)	1.60 (0.49, 5.24)	0.441	—	—	1.14 (0.38, 3.44)	0.811	—	—
Metastasis (cM1 vs cM0)	—	—	—	—	2.70 (0.86, 8.47)	0.088	—	—
Comorbidity (with vs without)	1.41 (0.50, 4.00)	0.522	—	—	0.95 (0.33, 2.71)	0.918	—	—

All factors where the value of univariate analysis is lower than 0.10 were involved in multivariate analysis; vs: versus; pN+ includes pN1-2; ASA comprises graded IV and V; with comorbidities: defined as hypertension, diabetes mellitus, and single- and multiple-organ dysfunction.
