ADL = Activities of daily living; HOOS = Hip disability and Osteoarthritis Outcome Score; THA = total hip arthroplasty
Model 1: long duration of PT = bo + b1x (HOOS score) adjusted for BMI, age, sex, living status, and Short Form-12 Mental Component Summary scale and HOOS score baseline
In the other models comorbidities (musculoskeletal, non-musculoskeletal or sensory impairment and the frequency of comorbidities) and their interaction with recovery were also taken into account
