Relationship between Hb level and eGFR. Data represent a cross-sectional survey of individuals randomly selected from the general US population (NHANES III). Median and 95% confidence limits around the 95th and 5th percentiles are shown for males and females at each eGFR interval. Adapted with permission.27

Prevalence of anemia by CKD stage. Anemia, defined as an Hb level less than 13.0 g/dL in males and less than 12.0 g/dL in females, was plotted by stage of CKD in results from NHANES III compared with NHANES IV. USRDS

Prevalence of low Hb level by eGFR in patients with diabetes compared with the general population. Open circles (○) indicate the diabetic population, while closed circles (●) represent general population data from NHANES III. A: Hb ≤11 g/dL; B: WHO criteria (men, Hb <13 g/dL; women, Hb <12 g/dL).

9. Fig 10
Changes in Hb levels and eGFR over 2 years in adult patients with CKD stages 3 and 4 not treated with ESA. Oral iron supplements and occasional IV iron treatment were administered to maintain TSAT at greater than 20% and ferritin levels greater than 100 ng/mL. Data given as mean ± SD. Although mean Hb levels showed little or no change, the number of study patients remaining without ESA therapy declined. Results courtesy of the authors, from control group patients previously described. Reprinted with permission.39

10. Fig 11
Distribution of Hb levels in adult males and females by age group. The 5th, 50th, and 95th percentiles are shown for each age group. In females, results reflect only individuals with serum ferritin greater than 25 ng/mL or TSAT greater than 16% because lower values may contribute to low Hb levels. Dash-dot-dash lines indicate recommended cutoff value to define anemia. (Source: US Renal Data System [USRDS] special data request, NHANES data set).
