Table 2 Linear regression analyses to identify the relationship of abduction at diagnosis and follow-up of the affected and nonaffected hip to age at diagnosis (adjusted for sex and abduction at diagnosis). With increasing age (in years) a decrease of range of abduction was seen (Estimate in degree)
Age at diagnosis | Est. | 2.5% | 97.5% | p |
|---|---|---|---|---|
In relation to range of abduction LCPD hip at diagnosis | −3.3 | −4.3 | − 2.3 | < 0.001 |
In relation to range of abduction nonaffected hip at diagnosis | −1.4 | −2.3 | −0.6 | < 0.001 |
In relation to range of abduction LCPD hip at follow-up | −3.1 | −4.4 | −1.8 | < 0.001 |
In relation to range of Abduction nonaffected hip at follow-up | −1.3 | −2.5 | −0,2 | < 0.05 |
