Significance of preoperative peripheral blood neutrophil-lymphocyte ratio in predicting postoperative survival in patients with multiple myeloma bone disease

Table 3 Comparison of 1-year, 3-year and 5-year cumulative survival rates between the high and the low neutrophil-lymphocyte ratio group

Cutoff value of NLR	1-yr CSRa	3-yr CSRa	5-yr CSRa	Chi-square	P value
NLR ≥ 4	41.7% vs 82.5%	10.4% vs 60.9%	0.0% vs 41.7%	15.969	0.000a
NLR ≥ 3 (n = 26)	52.0% vs 87.3%	19.1% vs 67.2%	0.0% vs 48.3%	22.192	0.000a
NLR ≥ 2	65.8% vs 88.9%	46.5% vs 61.1%	31.0% vs 34.0%	2.015	0.156
NLR ≥ 1	75.3% vs 85.7%	52.6% vs -	30.6% vs -	0.459	0.498
