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

Table 6 One-way ANOVA results of peripheral blood absolute lymphocyte counts, absolute neutrophil counts and neutrophil-lymphocyte ratio of the 82 multiple myeloma bone disease patients at different time points (mean ± SD)

Characteristic	Before operation	1 wk after operation	1 mo after operation	Last follow-up visit	F	P value
Absolute blood lymphocyte counts	1.34 ± 0.75	1.19 ± 0.55	1.45 ± 0.76	1.15 ± 0.821,2	2.382	0.070
Absolute neutrophil counts	3.87 ± 2.07	4.79 ± 2.373-5	3.72 ± 1.96	3.36 ± 2.04	4.376	0.005
NLR	2.78 ± 1.976,7	4.56 ± 2.33	3.14 ± 2.198	5.03 ± 6.73	4.998	0.002
Lymphocyte percentages (%)	25.09 ± 9.96	18.19 ± 7.193,4	26.66 ± 10.70	22.83 ± 12.68	5.770	0.001

¹When that at the last follow-up visit was compared to that 1 wk after operation, P = 0.055.

²When that at the last follow-up visit was compared to that 1 wk after operation, P < 0.05.

³When that 1 wk after operation was compared to that before operation, P < 0.05.

⁴When that 1 wk after operation was compared to that 1 mo after operation, P < 0.05.

⁵When that 1 wk after operation was compared to that at the last follow-up visit, P < 0.05.

⁶When that before operation was compared to that 1 wk after operation, P < 0.05.

⁷When that before operation was compared to that at the last follow-up visit, P < 0.05.

⁸When that 1 mo after operation was compared to that at the last follow-up visit, P < 0.05.
