A univariate Cox regression model was also designed to reveal the prognostic value of 25 CIFs in DLBCL patients of the meta-cohort that was enrolled by two GEO datasets (GSE10846 and GSE31312) after batch correction (Supplementary Figures 2A–D), and seven CIFs (CCL2, CSF2, IL15, IL17A, IL4, TGFA, and TNFSF10) were significantly associated with OS (Figure 2A and Supplementary Table 4). The gene discussed is IL4; the disease is diffuse large B-cell lymphoma.
