Association between age at pain onset and potentially relevant risk factors in the anteversion group

Parameter	HR	95% CI	p value
Combined anteversion	1.04	1.01–1.07	0.006

BMI	0.93	0.84–1.01	0.096
Sex (male/female)	0.90	0.44–1.69	0.72
History of DDH treatment (yes/no)	0.83	0.29–2.15	0.76

HR = hazard ratio; CI = confident interval; BMI = body mass index; DDH = developmental dysplasia of the hip.
