Table 3. Odds ratio (OR) and 95% confidence interval (CI) for nonvertebral fracture per standard deviation (SD) difference in each of cortical porosity, thickness, and cross-sectional area (CSA).
| Covariates in each of the models | OR (95% CI) | ||
|---|---|---|---|
| Cortical porosity | + 4.01% | Age, height, weight, FN aBMD | 1.39 (1.10–1.74) |
| FRAX alone | 1.53 (1.22–1.90) | ||
| Garvan alone | 1.45 (1.16–1.81) | ||
| Cortical thickness | – 0.58 mm | Age, height, weight, FN aBMD | 1.46 (1.15–1.85) |
| FRAX alone | 1.47 (1.17–1.83) | ||
| Garvan alone | 1.38 (1.10–1.73) | ||
| Cortical CSA | – 39.5 mm2 | Age, height, weight, FN aBMD | 1.06 (0.80–1.41) |
| FRAX alone | 1.02 (0.83–1.26) | ||
| Garvan alone | 0.94 (0.75–1.16) |
FN aBMD; femoral neck areal bone mineral density; FRAX, Fracture Risk Assessment Tool for calculation of the 10-year probability of a major osteoporotic fracture; Garvan, Fracture Risk estimate of the 10-year fracture risk for any fragility fracture.
FRAX and Garvan estimates are used log-transformed, and both estimates included FN aBMD.
