Table 1 Hip variables. Reported are correlation coefficient and 95% confidence interval. FEAR index and HOOS of the contralateral hip are significantly correlated (adjusted p = 0.03, correlation coefficient = 0.38), and Tönnis angle of AD severity and HHS of the contralateral hip are significantly correlated (adjusted p = 0.04, correlation coefficient = − 0.33)
