Change in the EQ-5D 3L index value in patients grouped by change in neurological deficit from admission to follow-up (N = 45).

Cohort (n = 45)	Change in EQ-5D 3L index value
Patients by change neurological deficit1; mean (95% CI)
Patients with new postoperative neurological deficit only, n = 13	0.11 (0.00 to 0.22)
All other patients, n = 32	−0.06 (−0.15 to 0.03)
Patients with new post- and with preoperative neurological deficit, n = 11	−0.03 (−0.15 to 0.09)
Patients without new post- and without preoperative neurological deficit, n = 13	−0.05 (−0.20 to 0.10)
Patients without new post- and with preoperative neurological deficit, n = 8	−0.12 (−0.37 to 0.13)

¹New neurological deficits were defined as new or worsened (transient/permanent) from surgery to the 3-month follow-up.
