| CAC score |
P-value | |||
|---|---|---|---|---|
| 1–100, N = 47 | 101–400, N = 39 | > 400, N = 57 | ||
| ObS/BS (%) | 1.46 ± 1.95 | 1.94 ± 3.85 | 1.84 ± 4.07 | 0.79 |
| OcS/BS (%) | 1.25 ± 1.36 | 1.33 ± 1.31 | 1.05 ± 1.13 | 0.54 |
| BFR/BS (mm3/cm2/year) | 1.40 ± 1.44 | 2.82 ± 2.10 | 2.37 ± 3.63 | 0.32 |
| Ac.f. (year − 1) | 0.31 ± 0.31 | 0.62 ± 0.47 | 0.49 ± 0.65 | 0.21 |
| BV/TV (%) | 19.58 ± 8.50 | 17.81 ± 5.92 | 19.45 ± 7.14 | 0.47 |
Between-group comparisons for continuous variables were performed using ANOVA. CAC, score coronary artery calcification score; iPTH, intact parathyroid hormone; OBS/BS, osteoblasts/bone surface; OCS/BS, osteoclasts/bone surface; BFR/BS, bone formation rate/bone surface; Ac.f., activation frequency; BV/TV, bone volume/tissue volume.
