Table 2:
Odds ratios per 1 SD decrease (OR, 95% CI) for associations of incident vertebral fracture (VF) with bone measurements at T8 and L2 vertebral level, adjusted for age, height and weight. Thoracic VF defined as T6-T10 and thoracolumbar VF as T11-L4.
| Any Level (n=135) | *Thoracic (n=53) | *Thoracolumbar (n=96) | |
|---|---|---|---|

| Int vBMD (mg/cm3) | 2.0 (1.5–2.8) | 2.9 (1.5–5.7) | 2.0 (1.4–2.8) |
| Trab vBMD (mg/cm3) | 2.0 (1.5–2.7) | 2.8 (1.5–5.3) | 1.9 (1.3–2.7) |

Among the 135 cases, 53 had fracture in the thoracic spine and of those 14 had also fracture in the thoracolumbar region. 96 cases had fracture in the thoracolumbar spine and of those 14 had also fracture in the thoracic region.
