Changes of radiological and clinical outcomes between the RA and control groups

Variable	RA group	Control group	P value
Radiological outcomes
Changes of compression rate (%)	11.56 ± 3.8%	7.02 ± 3.1%	< 0.05
Changes of local kyphotic angle (°)	3.77 ± 1.9	3.09 ± 1.6	< 0.05
Clinical outcomes
Changes of VAS	5.78 ± 0.72	5.92 ± 0.58	0.517
Changes of ODI	53.81 ± 6.52	58.65 ± 7.13	0.194

Values are given as mean ± SD. VAS indicates visual analog scale, ODI indicates Oswestry disability index. Changes of compression rate and local kyphotic angle showed the difference of compression rate and local kyphotic angle between preoperation and 1-year follow-up; Changes of VAS and ODI showed the difference in visual analog scale and Oswestry disability index between preoperation and 1-year follow-up
