LME categories of patients with DLBCL. (A) Kaplan-Meier models of PFS according to LME categories. (B) Kaplan-Meier models of OS according to LME categories. (C) Mantel-Haenszel χ2 of LME categories related to IPI risk group. (D-E) Forest plots visualize hazard ratios (HRs) and P values obtained from the multivariate analysis of LME categories and IPI for PFS and OS. (F) Distribution of IPI risk factors across different LME categories; ∗P < .05, ∗∗P < .01, and ∗∗∗P < .001.
