Table 5. Wedge angle (Pre-PVP and post-PVP).

PVP = percutaneous vertebroplasty; SEM = standard error of the mean; df = degree of freedom; NS = non-significant; S = significant

Period	Mean ± SD	SEM	t	df	P-value
Pre-PVP	20.5 ± 2.07	0.43	47.65	21	0.18 (NS)
One week	12.31 ± 1.70	0.36	33.96		0.015 (S)
Six months	11.9 ± 3.10	0.66	18.01		0.011 (S)
