CD4 and diffuse large B-cell lymphoma: In line with our previous molecular quantification (Figure 2A,B), the percentage of CD4+ T-cell in cHL was higher than in DLBCL, in which CD4+ T-cells accounted for only 18% (non-GCB DLBCL) and 17% (GCB DLBCL) of total cells (p = 0.002), respectively (Figure 2D).
