Figure 3. Prevalence of anemia, mild anemia, moderate anemia, and severe anemia among patients with different age.

Figure 3

The numbers of patients who were 18–39, 40–59, and ≥60 years of age were 1082, 708, and 158, respectively. A chi-square test was applied to compare differences in prevalence of anemia, mild anemia, moderate anemia, and severe anemia among patients with different age. The prevalence of anemia increased with increasing age (P = 0.026). The prevalence of mild anemia increased with increasing age (P<0.001). The prevalences of moderate anemia and of severe anemia did not differ significantly according to age (P = 0.098, P = 0.154).
