Multivariate model predicting DFS using NLR.

	DFS
Factor	Hazard ratio (95% CI)	P-value
Tumor size, T2-T4 vs. T1	2.503 (1.023–6.126)	0.044
Lymph node N1–3 vs. N0	1.453 (0.596–3.541)	0.411
Histology grade, III vs. I/II	1.440 (0.792–2.618)	0.232
Clinical stage, III vs. I/II	2.253 (1.041–4.876)	0.039
NLR	1.435 (0.803–2.563)	0.223

DFS, disease-free survival; NLR, neutrophil-to-lymphocyte ratio; CI, confidence interval.
