Baseline characteristics of surgical and nonsurgical groups

	Surgery
Baseline Characteristics	No n = 23	Yes n = 29	P Value^*	Unadjusted OR (95% CI)
No deformity	15 (65%)	14 (48%)	.22
Borderline deformity	8 (35%)	15 (52%)
Female	21 (91%)	27 (79%)	.28^†
Age (y)	32.8 ± 11	35.8 ± 11	.30
BMI (kg/m²)	25.3 ± 7	25.9 ± 5	.70
Duration of pain (mo)	17.4 ± 21	16.1 ± 14	.79
Numeric Pain Scale, 0–10	7.22 ± 2.5	6.75 ± 2.2	.47
SF-12 PCS	42.2 ± 7	40.2 ± 7	.30
SF-12 MCS	40.2 ± 8	40.6 ± 8	.87
Nonarthritic hip score	67.3 ± 14	63.3 ± 14	.32
Baecke total score	7.35 ± 1.2	8.40 ± 1.4	.02	1.89 (1.11–3.22)

OR = odds ratio; CI = confidence interval; BMI = body mass index; SF-12 PCS = physical composite subscore; SF-12 MCS = mental health composite subscore.

P value compares groups by logistic regression predicting surgery. Unadjusted ORs reflect the increased odds of undergoing surgery for a 1-unit increase in the variable and are reported when the P value is significant.
