Table 3. Multivariate survival analysis of overall survival of all patients, and patients without TisN0M0.

Clinical factors	Multivariate analysis of all patients (n=265)					Multivariate analysis, excluding TisN0M0 patients (n=214)
	HR	95% CI		P value		HR	95% CI		P value
		Lower limit	Upper limit				Lower limit	Upper limit
Gender	1.097	0.624	1.927	0.75		1.213	0.690	2.130	0.50
Operation time	1.007	1.002	1.012	0.005*		1.007	1.002	1.012	0.01*
MHR	24.837	7.265	84.911	<0.001*		27.097	8.081	90.867	<0.001*
T stage	1.471	1.048	2.065	0.03*		1.161	0.772	1.744	0.47
N stage	1.412	1.020	1.956	0.04*		1.429	1.009	1.837	0.045*

T stage and N stage were performed using the American Joint Committee on Cancer TNM staging system, 9th edition. *, P<0.05. CI, confidence interval; HR, hazard ratio; MHR, monocyte-to-high-density lipoprotein ratio; N, lymph node; T, tumor; TNM, tumor-lymph node-metastasis.
