Hematologic and biochemical parameters before initiation of darbepoetin treatment
| N | Mean | SD | |
|---|---|---|---|
| Starting packed cell volume (PCV) (%) | 33 | 20 | 4.1 |
| Baseline PCV (%) | 33 | 21.8 | 3.1 |
| MCV (fL) | 31 | 67.8 | 7.0 |
| MCHC (g/dL) | 31 | 33.9 | 1.6 |
| Absolute reticulocyte count (×103/μL)a | 26 | 20.7 | 0–88.5 |
| Platelet count (×103/μL) | 30 | 440 | 242 |
| BUN (mg/dL) | 33 | 110 | 49.7 |
| Creatinine (mg/dL) | 33 | 6 | 2.5 |
| Phosphorous (mg/dL) | 33 | 9.4 | 3.8 |
| Potassium (mmol/L) | 33 | 4.9 | 0.8 |
Starting PCV is the PCV at the time treatment with darbepoetin was initiated. Baseline PCV reflects an initial increase in PCV due to a concurrent packed red blood cells transfusion.

Absolute reticulocyte count was not normally distributed; the median and range are reported.
