Figure 3. Overall survival and progression-free survival in patients with red blood cell distribution width (RDW) ≥16% versus <16%. (A) The median OS for patients with RDW ≥16% and <16% was 5.4 (95%CI=1.2-10.8) and 16.2 (95%CI=8.4-not reached) months (p=0.010), respectively. (B) The median PFS for patients with RDW ≥16% and <16% was 2.1 (95%CI=0.4-6.2) and 4.7 (95%CI=1.9-6.8) months (p=0.120), respectively.
