BMP6 and diffuse large B-cell lymphoma: We performed the survival analysis of BMP ligands and receptors in the cohort of NCICCR‐DLBCL patients (n = 186).[36] The levels of BMP6, BMP7 and ACVR1 significantly correlated with better survival outcome probability (Figure 7H–J), especially the level of BMP7 (P value = 0.0006).
