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

Figure 2 Comparison of white blood cell count or ratio between preoperation, 1 wk after the operation, 1 mo after the operation and the last follow-up visit in multiple myeloma bone disease patients. A: The absolute neutrophil count increased significantly 1 wk after the operation and returned to that before the operation 1 mo after the operation; B: The peripheral blood absolute lymphocyte count declined after the operation, returned to that before the operation 1 mo after the operation, and returned to a low level at the last follow-up visit; C: Peripheral blood neutrophil-lymphocyte ratio; D: Lymphocyte percentage. NLR: Neutrophil-lymphocyte ratio.
