Table 1 Baseline characteristics of patients in the study. Data were expressed as mean ± SD for continuous variables and as number (percentages) for categorical variables. RDW_SD: red blood cell distribution width standard deviation; DS stage: Durie-Salmon stage; ISS stage: international staging system stage; PLR: platelet-to-lymphocyte ratio; hb: hemoglobin; plt: platelet; ALB: serum albumin; LDH: lactate dehydrogenase; cr: serum creatinine; ca: calcium; 2-MG: 2-microglobulin; ASCT: autologous stem cell transplantation.
