Figure 1: Receiver operating characteristics curves (ROC) and area under the curve (AUC) to identify best cut-off points for absolute lymphocyte count at day 15 (ALC-15); absolute monocyte count at day 15 (AMC-15); and absolute lymphocyte count/absolute monocyte count ratio at day 15 (ALC/AMC-15) for the binary clinical outcome �death/survival� established at 5 years post-autologous peripheral hematopoietic stem cell transplantation (APHSCT). (a) ALC-15 = 500 cells/�l had an AUC of 0.75 with a sensitivity of 76% and specificity of 69%. (b) AMC-15 = 600 cells/�l had an AUC of 0.70 with a sensitivity of 72% and specificity of 67%. (c) ALC/AMC-15 = 1 had an AUC of 0.85 with a sensitivity of 84% and a specificity of 79%.
