Relationship between reactive oxygen metabolite (ROM) levels and patient characteristics.

Number of cases	ROM before surgery (U.CARR)	Sex (male/female)	Age (years)	Cause of disorder (LSS/LDH)	Smoking (±)	Diabetes (±)	Surgical procedure (decompression/fusion)	Surgical time (min)	Bleeding during surgery (g)
80	(193-755)	44/36	(22-88)	64/16	10/70	19/61	44/36	(86-398)	(5-341)

ROM: reactive oxygen metabolites; LSS: lumbar spinal stenosis; LDH: lumbar disc herniation. Data are (range).
