Prognostic impact of sCD19 levels, CC, FCM, and their combination in CSF samples from DLBCL and BL patients screened for CNS disease. EFS (A,C,E,G,I,K) and OS (B,D,F,H,J,L) curves are separately shown for DLBCL (A-F) and BL (G-L) cases, classified according to their CSF status as defined by sCD19 levels in both the whole patient group (A-B,G-H) and among only FCM⁻ cases (C-D,I-J), and by CC and FCM in combination with sCD19 (E-F,K-L).
