On univariate analysis, factors associated with worse PFS included ECOG performance status ≥2 (vs. ≤1: p=0.041), Ann Arbor clinical stage (CS) ≥3 (vs. ≤2: p<0.001), G≥2 anemia (vs. G≤1: p=0.001), serum albumin <3.5 g/dL (vs. ≥3.5 g/dL: p=0.008), and BM involvement (vs. negative: p<0.001). Here, ALB is linked to anemia.
