CISD2 and diffuse large B-cell lymphoma: Also, DLBCL with high CISD2 expression showed remarkably worse progression-free survival (PFS) than low CISD2 expression in both the GSE31312 dataset (HR = 0.774, 95% CI: 0.614-0.976, P = 0.028) and the GSE93984 dataset (HR = 0.297, 95% CI: 0.086-1.029, P = 0.009) (Figures 3B, D).
