p-Value | |
|---|---|---|---|
| BVF (%) | 17.07 ± 4.69 | 20.39 ± 3.31 | 0.018 * |
| Tb.Th (µm) | 159 ± 16 | 179 ± 14 | <0.001 *** |
| Tb.Sp (µm) | 549 ± 40 | 557 ± 38 | 0.541 |
| Conn.D (mm−3) | 6.03 ± 2.30 | 5.92 ± 1.58 | 0.874 |
| DA (n) | 1.87 ± 0.20 | 1.20 ± 0.62 | <0.001 *** |
| SMI | 1.87 ± 0.28 | 1.83 ± 0.19 | 0.599 |
The data apply for normally distributed parameters as mean values ± standard deviation (M ± SD); BVF, bone volume fraction; Tb.Th, trabecular thickness; Tb.Sp, trabecular separation; Conn.D, connectivity density; DA, degree of anisotropy; SMI, structure model index; CC, craniocaudale puncture; VD, ventrodorsale puncture; P, independent Student’s t-test. The levels of significance are p < 0.05 * and p < 0.001 ***.
