Measurements of serum calcium, phosphorus and iPTH levels based on hemoglobin values by stratification.
| Hb (g/L) | <60 (n = 5) | 60–90 (n = 52) | 90–110 (n = 93) | 110–130 (n = 73) | >130 (n = 17) | P value |
|---|---|---|---|---|---|---|
| Ca (mmol/L) | – | 2.23 ± 0.03 | 2.28 ± 0.02 | 2.34 ± 0.02 | 2.32 ± 0.04 | |
| P (mmol/L) | – | 2.06 ± 0.09 | 2.11 ± 0.06 | 2.04 ± 0.07 | 2.03 ± 0.12 | |
| iPTH (pg/mL) | – | 596.41 ± 86.17 | 506.81 ± 49.79 | 435.62 ± 69.56* | 388.59 ± 83.59 |
No statistically significant differences were found among the groups, except *P = 0.042 vs. patients with Hb within 90–110 g/L.
