Survival analysis of DLBCL patients. (A-B) Comparison of PFS based on the presence or absence of febrile neutropenia and the abundance of Enterobacteriaceae. (C) Comparison of PFS based on stage and abundance of Enterobacteriaceae. (D-E) Associations of the abundance of Enterobacteriaceae with the serum levels of IL-6 and IFN-γ. (F) Network analysis of genera belonging to Enterobacteriaceae and significantly correlated genera. The color of the nodes indicates the phylum to which they belong, and the color of the edge indicates the Spearman correlation coefficient between nodes. (G) A suggested adjuvant prophylactic treatment plan based on the microbiome for preventing adverse events in patients with DLBCL.
