	Factor	Male	Female	Consolidated sex	value
CLBP group	Disease course	34.55 ± 43.10	65.15 ± 53.12	49.85 ± 50.20	0.057
	JOA score	18.10 ± 3.59	19.80 ± 3.33	18.95 ± 3.52	0.080
	VAS score	4.50 ± 1.35	4.00 ± 1.41	4.25 ± 1.39	0.218
	Cobb angle	40.80 ± 7.92	40.25 ± 10.83	40.52 ± 9.37	0.735
Control group	Cobb angle	39.60 ± 9.48	39.00 ± 7.84	39.30 ± 8.59^&	0.432

Note. Values are presented as mean ± standard deviation. CLBP: chronic low back pain; JOA: Japanese Orthopedic Association; and VAS: visual analog scale. value was derived from nonparametric Mann–Whitney U test for men and women of the CLBP group. Note. ^&indicates no statistically significant difference.
