Anemia after gastrectomy for early gastric cancer: Long-term follow-up observational study

Figure 1 Incidence and distribution of anemia after gastrectomy. IDA: Iron deficiency anemia; ACD: Anemia of chronic disease; MBA: Megaloblastic anemia.

Figure 2 Incidence of anemia, iron deficiency state, and vitamin B₁₂ deficiency state after gastrectomy.

Figure 3 Incidence of anemia and deficiency state after gastrectomy. A: Significantly higher incidence of anemia in female patients than in male patients at 12, 24, 36 and 48 mo after surgery, ^aP < 0.05 vs female group; B: Significantly higher incidence of anemia in patients with total gastrectomy (TG) than in patients with subtotal gastrectomy (STG) at 48 mo after surgery, ^aP < 0.05 vs STG group; C: Significantly higher incidence of iron deficiency state in female patients than in male patients at all times in the follow-up period except at 3 mo after surgery, ^aP < 0.05 vs male group; D: Significantly higher incidence of iron deficiency in patients with TG than in patients with STG at 36 mo after surgery, ^aP < 0.05 vs STG group.
