Predictors for quality of life improvement after surgery for degenerative cervical myelopathy: a prospective multi-center study

Table 5 Multiple regression analysis: independent predictors of increased EQ-5D score from preoperative assessment to 1 year after surgery

Factor	β	95% CI	P
EQ-5D	− 0.493	− 0.707 to − 0.279	< 0.001
LL	0.006	0.003 to 0.010	0.001
SS	− 0.008	− 0.013 to − 0.003	0.004
TPA	0.004	0.001 to 0.007	0.02

An increase in EQ-5D score from preoperative assessment to 1 year after surgery was defined as EQ-5D score at 1 year after surgery—preoperative EQ-5D score
