ROC curve analysis of independent risk factors and IPI/aaIPI score for predicting survival in HIV-associated DLBCL patients. The ROC curves illustrate the predictive performance of β2-M level, CD8 + T cell count, LDH, and non-receipt of standard treatment for 1-year (A), 3-year (B), and 5-year (C) survival. ROC, Receiver Operating Characteristic; β2-M, beta-2 microglobulin; IPI, international prognostic index; aaIPI, age adjusted IPI; LDH, lactate dehydrogenase.
