  1. Values are mean (standard deviation), with the exception of HHS values which are median (range); *p < 0.05 – hip osteoarthritis group significantly different to control group; ¢Most symptomatic hip for participants with bilateral hip osteoarthritis and randomly assigned hip for control participants; †HHS scale – 0 = extreme hip problems and 100 = no hip problems; ηHHS pain subscale – 0 = extreme hip related pain and 44 = no hip related pain; ΩHHS function subscale – 0 = extreme hip related dysfunction and 47 = no hip related dysfunction; δKellgren-Lawrence grading scale – 0 = no radiographic features of hip osteoarthritis and 4 = large osteophytes; OA – osteoarthritis
