Table 4. New fractures of different treatments.

PVP	/	2.05(0.92–4.6)
1.6(0.28–4.3)	BK	1.46(0.8–2.7)
2.4(0.73–5)	2.2(0.7–4.7)	CT

For new fractures, odds ratios (ORs) higher than 1 favor the column-defining treatment. Direct comparsions were shown in the upper right. Indirect comparsions were shown in the bottom left. The number which was painted by a style of overstriking indicated there was a significant difference between two treatments. PVP: Percutaneous vertebroplasty; BK: Balloon kyphoplasty; CT: Conservative treatment.
