Table 3.

Associations of bone measurements at T10 and L3 with prevalent moderate/severe vertebral fractures by fracture location. OR (95 % CI, per 1SD decrease) are shown for combined group (all fracture locations), upper spine fractures (T4–T10) and lower spine fractures (T11–L4). ORs in italics are significant (p<0.05)

	All fractures (40 cases, 80 controls)	Upper spine fractures (17 cases, 34 controls)	Lower spine fractures (20 cases, 40 controls)
