2. Fig 1
Mean WOMAC Osteoarthritis Index scores ± SD in groups with different grades of hip OA (A) according to both limbs and (B) according to the side more severely affected. Radiographic grading was made according to Li et al.13 ∗P<.05, differences between the radiographic OA subgroups (n=8–11) (Kruskal-Wallis test).

Mean PROM ± SD in patients with different grades of hip OA. Radiographic grading was made according to Li et al.13 ∗P<.05; †P<.01; differences between the radiographic OA subgroups (n=8–11) (Kruskal-Wallis test).

Mean PROM ± SD of the hip in controls (n=29–30) and men with hip OA (n=26). ∗P<.01; †P<.001 (Student t test).

5. Fig 4
Mean differences in PROM ± SD within the hip OA group, when the radiographic scoring difference is ≥1 grade (n=20). Radiographic grading was made according to Li et al.13 ∗P<.05; †P<.01 (paired t test).

Mean functional tests ± SD in controls (n=21–29) and in men with hip OA (n=20–27). ∗P<.01; †P<.001 (Student t test).

Differences in 1-leg functional tests in OA group, when the radiographic scoring difference is ≥1 grade (n=18–21). Radiographic grading was made according to Li et al.13 There were no significant differences between sides (paired t test).
