Fig. 4.
Macrophage polarization and International Prognostic Index. The figure shows CD68, CD163 and CD163/CD68 ratio, and the International Prognosis Index in EBV-negative DLBCL (a–c) and EBV + DLBCLe (d–f). p values were obtained by the Mann–Whitney test. An association between IPI > 2 and higher CD163/CD68 ratio was found in EBV-negative DLBCL
