Table 5. Association between NLR before metastatic brain lesion surgery and DFS, OS.

NLR before brain surgery	N (%)	DFS (months)			OS (months)
		Median (95% CI)	P		Median (95% CI)	P
>3.0553	5 (45.5)	3 (0.583–5.147)	0.724		10 (5.706–14.294)	0.091
≤3.0553	6 (54.5)	7 (3.399–10.601)			27 (8.756–45.244)

NLR, neutrophil-to-lymphocyte ratio; OS, overall survival; DFS, disease-free survival.
