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

Figure 1 Comparison of survival time of different neutrophil-lymphocyte ratio groups. A: Comparison of postoperative survival (POS) in patients within the neutrophil-lymphocyte ratio (NLR ≥ 1) group and NLR < 1 group, among which the POS of patients in the NLR ≥ 1 group and the NLR < 1 group showed no significant difference (P > 0.05); B: The POS of patients in the preoperative peripheral blood NLR ≥ 2 group and the NLR < 2 group showed no significant difference (P > 0.05); C: The POS of patients in the preoperative peripheral blood NLR < 3 group was significantly longer than that in the NLR ≥ 3 group (P < 0.05); D: The POS of patients in the preoperative peripheral blood NLR < 4 group was significantly longer than that in the NLR ≥ 4 group (P < 0.05). NLR: Neutrophil-lymphocyte ratio.
