  1. Data are shown means ± SD with 95% confidence interval in parenthesis. AD acetabular dysplasia, CT computed tomography, CE center edge, ADR acetabular depth ratio, AHI acetabulum head index, AASA anterior acetabular sector angle, PASA posterior acetabular sector angle, VCA vertical-center-anterior margin angle. *Males vs females, evaluated with the Mann–Whitney U test. P values < 0.05 were considered statistically significant
