Fig. 2. Graph showing differences in hemoglobin concentrations at 6 weeks after surgery compared to those at the preoperative assessment (Pre–6 wk), immediately after surgery (Post–6 wk), and at 1 week after surgery (1 wk–6 wk). The amount of recovered hemoglobin concentration at 6 weeks was significantly greater in the IV-FCM group than in the control group at all intervals. *p < 0.05.
