Optimal Cut-Off Value of the Superior Articular Process Area as a Morphological Parameter to Predict Lumbar Foraminal Stenosis

Table 1

Comparison of the characteristics of control and LFS groups.

Parameter	Control group; ()	LFS group; ()
Gender (male/female)	85/82	66/71; (NS)
Age (years)	73.85 ± 8.38	71.95 ± 8.05; (NS)
VAS score		5.9 ± 1.1
SAPA (mm^2)	96.31 ± 13.60	128.13 ± 17.23; ()

Data represent the mean ± standard deviation (SD) or the numbers of patients.
LFS: lumbar foraminal stenosis; VAS: visual analog scale; SAPA: superior articular process area; NS: not statistically significant ().
